Find the limit. Modified from Parks and Plates: The Geology of our National Parks, Monuments and Seashores, by Robert J. Lillie, New York, W. W. Norton and Company, 298 pp., 2005, www.amazon.com/dp/0134905172. 1 Volcano Lab using Google Earth Tm Name: _____ Date _____ Purpose: To be able to describe and identify the common volcano types, tectonic setting, and geographic location. Most shield volcanoes are associated with mantle plumes, although some form at divergent boundaries, either on land or on the sea floor. The Siberian Traps (also basalt), which erupted at the end of the Permian period at 250 Ma, are estimated to have produced approximately 40 times as much lava as the CRBG. Descabeza Mt. Its elevation is 4,169 m above sea level. Mount Alayta in Ethiopia, Africa is a massive shield volcano. There is no Emissions History data available for Alayta. The Atlantic Coastal Plain is covered by sedimentary layers of the modern passive continental margin. The crust beneath the growing mountains remained relatively thin. Alayta shield volcano (left-center) covers an area of 2,700 km 2 in the western Danakil depression. The Indian continent became part of East Gondwana, together with Australia and Antarctica. Elsewhere along the collision zone, the Ouachita and Marathon mountains are foreland fold-and-thrust belts similar to the Valley and Ridge Province, and include Hot Springs National Park in Arkansas and a small part of Big Bend National Park in Texas. Rather, the hot springs occur because there are cracks in chert layers outside the park that allow rainwater to circulate slowly downward, where it is heated due to the normal increase in temperature with depth in the Earth. The long mountain ranges and rift valleys were similar to those forming today in East Africa and the Basin and Range Province. The Sub-Himalayan tectonic plate is sometimes referred to as the Cis-Himalayan tectonic plate in the older literature. (Figure 4.10), are typically only a few hundred metres in diameter, and few are more than 200 m high. There are few 'hot spots' on Earth and the one under Hawaii is right in the middle of one of the largest . counting off seconds), and the direction of travel (by turns The two main types of textures created during effusive subaerial eruptions are pahoehoe and aa. By that time, its neighbour, Loihi, will have emerged from the sea floor, and its other neighbours, Mauna Loa and Mauna Kea, will have become significantly eroded, like their cousins, the islands to the northwest (Figure 4.15). Paleogeographic map from Ron Blakey, Northern Arizona University, http://cpgeosystems.com/paleomaps.html. What is the average rate of advance of the flow front from June 27 to October 29, 2014, in m/day and m/hour? . It is also considered one of. The Valley and Ridge Province is composed of sedimentary layers of the ancient continental margin that were folded and faulted during the collision. What quantity of heat is released for each mole of water formed? In their prime they probably had peaks as high as those in the modern zone of continental collision stretching from the Himalayas in Asia to the Alps in Europe. These sediments are thrust over the Sub-himalayan range along the Main Boundary Thrust (MBT). you know that you are taken along the following course: Most cinder cones are monogenetic, meaning that they formed during a single eruptive phase that might have lasted weeks or months. However, this volcano didn't have as many eruptive characteristics as the one before it. The Mount Isa Inlier of NW Australia is a giant metallogenic province that hosts world class Pb-Zn (Ag, Cu), Cu-Au (Mo, Co, U) and U-REE deposits. These molasse deposits, known as the "Murree and Sivaliks Formations", are internally folded and imbricated. A fumarole is an opening in the Earth's crust that releases steam and gases. After eroding away up to 10 miles (16 kilometers) of rock, there is still a small crustal root that maintains mountain heights much greater than those seen today in the Appalachians. 2.1 Electrons, Protons, Neutrons, and Atoms, 4.5 Monitoring Volcanoes and Predicting Eruptions, 5.3 The Products of Weathering and Erosion, 6.3 Depositional Environments and Sedimentary Basins, 7.5 Contact Metamorphism and Hydrothermal Processes, 9.1 Understanding Earth through Seismology, 10.1 Alfred Wegener the Father of Plate Tectonics, 10.2 Global Geological Models of the Early 20th Century, 10.3 Geological Renaissance of the Mid-20th Century, 10.4 Plates, Plate Motions, and Plate-Boundary Processes, 11.5 Forecasting Earthquakes and Minimizing Damage and Casualties, 15.1 Factors That Control Slope Stability, 15.3 Preventing, Delaying, Monitoring, and Mitigating Mass Wasting, 21.2 Western Canada during the Precambrian, Chapter 22 The Origin of Earth and the Solar System, Karla Panchuk, Department of Geological Sciences, University of Saskatchewan, 22.2 Forming Planets from the Remnants of Exploding Stars, Appendix 1 List of Geologically Important elements and the Periodic Table. If its volcanic activity ceases, it might erode away within a few tens of thousands of years. Open up the worksheet from the lesson. upset because you told them political science is not a real science). 2). Center the image so that the capital, Santiago, is in your screen at an eye altitude of ~1000 km. Wiki User. Cinder cones are much smaller. This subduction zone has created both the Aleutian Trench, about 270 miles to the southeast of the volcano, and the Aleutian volcanic arc, of which Redoubt is a part. Using the scale bar in the lower left of the map, estimate the average distance between the subduction boundary and the Cascadia composite volcanoes. Support your answer with observations on the major tectonic landforms of the region. Mount Pinatubo is a composite volcano in the Philippines. In its mission and administration, it might arguably be considered the first site functioning as a national park. The first formal national park, Yellowstone, was established by act of Congress 40 years later. Alayta. Support your answer with observations on the major tectonic landforms of the region. Fuji . how to find base elevation of volcanomr patel neurosurgeon cardiff 27 februari, 2023 / i how old was stewart granger when he died / av / i how old was stewart granger when he died / av The latest is the ongoing continental rifting forming the Rio Grande Rift arm of the Basin and Range Province. Although it is not a prominent mountain (Figure 4.9), Kilauea volcano has a large caldera in its summit area (Figure 4.16). In the western part of the Appalachian Mountains, the rocks were originally part of North America. A visit to one of those sites reveals not only beautiful mountain scenery, but also rocks and topography that tell a story of ancient episodes of drifting plates and crashing continents. The spectacular scenery of the park lies within the Blue Ridge Province, with a small portion on the northwest in the Valley and Ridge Province. Aa, or blocky lava, forms when magma is forced to flow faster than it is able to (down a slope for example) (Figure 4.19c). Mauna Loa, the worlds largest volcano and the worlds largest mountain (by volume) last erupted in 1984. [1] It is located in the Afar Region or Triangle, which is a high in volcanic activity. what is the most active volcano in the Cascade range? Use lHospitals Rule where appropriate. An almost complete stratigraphic record ranging from the Upper Proterozoic to the Eocene is preserved within the sediments of the TH. A 100-200 m thick glacier covers the upper part of the volcano and its elliptical 2.5-km-wide summit crater or caldera. As the ocean widened, the edge of ancient North America subsided, and a blanket of sedimentary layers buried the rift valleys and eroded mountain ranges. The Appalachian Mountains extend from the Maritime Provinces of Canada all the way to northern Georgia and Alabama. The last eruption was in 1915. (5 pts) d. What type of the volcano is Mt Fuji, based on size, shape, and composition? [1] It is located in the Afar Region or Triangle, which is a high in volcanic activity. This last feature earned the Himalaya its name, originating from the Sanskrit for "the abode of the snow". St. Helens has erupted the most throughout its entire history. Redoubt: Plate Tectonic Setting. After damaging some infrastructure west of Pahoa, the flow stopped advancing. Each zone, flanked by the thrust faults on its north and south, has stratigraphy (type of rocks and their layering) different from the adjacent zones. Figure 4.3 The plate-tectonic settings of common types of volcanism. Krakatoa lies along the convergence of the Indian-Australian and Eurasian tectonic plates, a zone of high volcanic and seismic activity. But in many places along the Himalayan belt, this transition zone is marked by a major structure, the "Central Himalayan Detachment System", also known as the "South Tibetan Detachment System" or "North Himalayan Normal Fault", which has indicators of both extension and compression. The damage took place on the land and and properties. Very small-scale maps (such as world maps) are not included. The lithosphere rests on and slides over an underlying partially . Farther east, the rocks formed elsewhere and were attached (accreted) to the edge of North America as the ocean closed. [7] The change of the relative speed between the Indian and Asian plates from very fast (18-19.5cm/yr) to fast (4.5cm/yr) at about 55Ma[8] is circumstantial support for collision then. These, and some minor gases, originate from the magma chamber at depth and rise up through cracks in the overlying rock. Whenever you search in PBworks, Dokkio Sidebar (from the makers of PBworks) will run the same search in your Drive, Dropbox, OneDrive, Gmail, and Slack. There is data available for 2 confirmed Holocene eruptive periods. Map of the Earth's tectonic plates. They can extend up to several thousand metres from the surrounding terrain, and, with slopes ranging up to 30, are typically up to 10 km across. Even though it is more than reasonable to argue that this huge amount of crustal shortening most probably results from a combination of these three mechanisms, it is nevertheless the last mechanism which created the high topographic relief of the Himalaya. A chain of younger craters are aligned along a north-northwest axis in the basaltic-to-trachytic shield along the east side of the . Iapetus Ocean Closes. R[n|hzB #7uqEpJPuOyEb^;VzN_vcnkR)47JDA-^RP j @LDkO55+Ev'/{afq"O`:V Nl$L_1$OW All of the Hawaiian volcanoes are related to the mantle plume that currently lies beneath Mauna Loa, Kilauea, and Loihi (Figure 4.15). Now you can find what you're looking for wherever it lives. About 750 million years ago a very ancient supercontinent began to rip apart. Abstract. Table 4.1 A summary of the important types of volcanism. Continents collide but continue to converge. Later rifting opened the Atlantic Ocean, isolating the mountains as separate ranges on different continents. Mount Taal is located in the Philippines and currently has 47 craters. In this area, the Pacific Plate is moving northwest at a rate of about 7 cm/year. Mt. The map shown here illustrates the interactions between the North America, Juan de Fuca, and Pacific Plates off the west coast of Canada and the United States. You don't have permission to comment on this page. Alayta, Ethiopia (12.887,40.573). 1 It is located in the Afar Region or Triangle, which is a high in volcanic activity. The Arctic Ocean opens on the north. This is largely because of the presence of pyroclastic eruptive material, which is not strong. The area of southwest Texas where the Rio Grande River takes a sharp turn to the north displays the effects of three superimposed tectonic episodes. 1). Great Falls Park lies on the eastern edge of the Piedmont Province, while the Blue Ridge Parkway and Shenandoah National Park lie entirely within the Blue Ridge Province. Alayta, Ethiopia (12.887, 40.573). The tectonic and structural setting of Mt Isa Inlier - implications for deposit models and exploration potential. Geology of northern Afar (Ethiopia). Background. Navigate to Santiago, Chile, in South America by typing in the city and country in the search bar . This immense mountain range began to form between 40 and 50 million years ago, when two large landmasses, India and Eurasia, driven by plate 3. elaborate on the concept of an "active" volcano Systematic variations in the composition of volcanism over the past several thousand years at Mt. Most other LIP eruptions are much bigger. All of the diamond deposits on Earth are assumed to have formed in this way; an example is the rich Ekati Mine in the Northwest Territories (Figure 4.22). Some of those rocks were buried more than 10 miles (15 kilometers) during the continental collision, then uplifted and exposed by a combination of thrust faulting, erosion, and isostatic rebound. Copy. Tip: To turn text into a link, highlight the text, then click on a page or file from the list above. Tectonic Setting.

"Nyimaling-Tso Morari Metamorphic Dome" in the Ladakh region, the "Tethys Himalaya synclinorium" passes gradually to the north in a large dome of greenschist to eclogitic metamorphic rocks. From about 400 to 300 million years ago the Iapetus Ocean gradually closed during subduction. It is sponsored by the, The IAVCEI Commission on Volcanic Hazards and Risk has a, Middle InfraRed Observation of Volcanic Activity (. By the first process, the rocks were compressed and shoved (thrust) upward along fault lines as the ocean closed and the continents collided. Its most recent eruption was in 1915.[1]. The Hawaiian volcanoes are riddled with thousands of old lava tubes, some as long as 50 km. In the case of divergent plate boundaries, where plates are spreading away from each other, the rate of plate movement plays an important role in determining the . Together, these plates constitute the lithosphere, from the Greek lithos, meaning " rock .". Volcano shape is strongly controlled by eruptive style, which in turn is controlled by magma composition and tectonic setting. 13 languages. Himalaya has Indo-Gangetic Plain in south, Pamir Mountains in west in Central Asia, and Hengduan Mountains in east on ChinaMyanmar border. Want to create or adapt OER like this? Tephra (lava fragments) is produced during explosive eruptions, and accumulates in the vicinity of cinder cones. Mount Alayta covers an area of 2,700 square kilometers southwest of Lake Afrera. Like continental volcanoes, submarine volcanoes are most common where tectonic plates move towards or away from each other. Type. VW is a higher education, k-12, and public outreach project of the Oregon Space Grant Consortium administered through the Department of Geosciences at Oregon State University.. Disclaimers and Policies | Login However, this volcano didn't have as many eruptivecharacteristics as the one before it. Stratigraphic analysis of these sediments yields important indications on the geological history of the northern continental margin of the Indian sub-continent from its Gondwanian evolution to its continental collision with Eurasia. The first mechanism also calls upon the subduction of the Indian continental crust below Tibet. From east to west the Himalayas are divided into 3 regions, Eastern Himalaya, Central Himalaya, and Western Himalaya, which collectively house several nations and states. Mount Alayta covers an area of 2,700 square kilometers southwest of Lake Afrera. "Geology and Petrographic study of the area from Chiraundi Khola to Thulo Khola, Dhading/Nawakot district, central Nepal". Shield volcanoes generally hold flat, broad appearances. Mount Alayta is an active shield volcano in the Afar Region of Ethiopia. A series of very recent craters is aligned along the NNW-trending axis of the basaltic-to-trachytic shield. The magma within a lava tube is not exposed to the air, so it remains hot and fluid and can flow for tens of kilometres, thus contributing to the large size and low slopes of shield volcanoes. 4. determine volcanoes with the greatest risk to people and properly using eruption history and population data. Tell what type of volcano it is, you can do an internet research for this information. St Helens is on the North American Plate situated above the subducted reminent of the oceanic Juan de Fuca plate. The Himalayas: Two continents collide Among the most dramatic and visible creations of plate-tectonic forces are the lofty Himalayas, which stretch 2,900 km along the border between India and Tibet. The mountains reach heights similar to those of the modern-day Alps, as the hard crust of northern Alaska breaks and uplifts. 1. Mt St Helens is a major stratovolcano in the Cascades Range, all of which have formed as a result of the ongoing subduction of the Juan de Fuca tectonic plate beneath the western coast of North America. number that is at the bottom far right of the screen. Describe the likely tectonic setting of the volcanoes in the Japanese region. Terms of use / Privacy policy / GDPR, About this workspace The Indian plate then broke off from Australia and Antarctica in the Early Cretaceous (130-125Ma) with the opening of the "South Indian Ocean" (Fig. The Blue Ridge Province is part of North Americas ancient continental margin, while the Valley and Ridge Province contains sedimentary layers of North America that were folded and faulted during the collision. St. Helens? Whenever you search in PBworks, Dokkio Sidebar (from the makers of PBworks) will run the same search in your Drive, Dropbox, OneDrive, Gmail, and Slack. Patrick Pringle, a volcanologist with the Washington State Department of Natural Resources, describes Mt. See answer (1) Best Answer. The Juan de Fuca Plate is forming along the Juan de Fuca ridge, and is then subducted beneath the North America Plate along the red line with teeth on it (Subduction boundary). The Gulf of Mexico ceased opening about 100 million years ago, when tectonic activity shifted eastward to the Caribbean region. National Park Service sites in the Appalachian Mountains have rocks and landscapes resulting from collision of North America with accreted terranes and the ancient continent of Gondwanaland. (2 pts), To get the height you will need to move the mouse over the area and then look at the. illustrations above modified from Parks and Plates: The Geology of our National Parks, Monuments and Seashores, by Robert J. Lillie, New York, W. W. Norton and Company, 298 pp., 2005, www.amazon.com/dp/0134905172. Eventually, the entire Iapetus Ocean closed and the continents collided to form the supercontinent of Pangea. Database of Raman spectroscopy, X-ray diffraction and chemistry of minerals Prior to 1980, Mt St Helens was a classical cone-shaped volcano, and a well-visited site on the tourist trail. Learn how BCcampus supports open education and how you can access Pressbooks. 100 Million Years Ago Great Smoky Mountains National Park is the most visited unit in the entire National Park System, attracting more than 11 million people per year. The kimberlites at Ekati erupted between 45 and 60 Ma. Confirmed Eruption Iapetus Ocean Completely Closes. As the margin cooled and subsided, thick sedimentary strata covered the earlier mountains and rift valleys. In the Norian (210Ma), a major rifting episode split Gondwana in two parts. 120 Million Years Ago Lava tubes form naturally and readily on both shield and composite volcanoes because flowing mafic lava preferentially cools near its margins, forming solid lava leves that eventually close over the top of the flow. There is no Deformation History data available for Alayta. In 1915, Mount Alayta exploded at the same VEI level of 2. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. Now you can find what you're looking for wherever it lives. The second process (isostasy) results in the wholesale uplift of a broad region as the crust thickens. A new outbreak occurred November 1, branching out to the north from the main flow about 6 km southwest of Pahoa. The Appalachians are part of a larger zone of continental collision that includes the Marathon and Ouachita mountains in the southern United States, the Atlas Mountains in Africa, and the Caledonide Mountains in Greenland, the British Isles, and Scandinavia. Go to Google Earth. Learning Goals: 1. describe common types of volcanoes using satellite imagery 2. use your date and observations of satelite data to relate volcano type, tectonic setting, volcanic hazards, and magma chemistry 3. elaborate on the concept of an "active" volcano 4. determine volcanoes with the greatest risk to people and properly using eruption Confirmed Eruption Hot, fast-moving pyroclastic flows and lahars are the two main causes of casualties in volcanic eruptions. During historical times, the floors of both Kilauea caldera and Halemaumau crater have moved up during expansion of the magma chamber and down during deflation of the chamber. In their prime, Ouachita peaks probably rose to no more than the modest height (~9,000 feet; 2,750 meters) of the Carpathian Mountains in central Europe. This compilation of synonyms and subsidiary features may not be comprehensive. If there is a more elementary method, consider using it. Eyjafjallajkull products have an alkaline composition, similar to other off-rift volcanoes in Iceland. Granitoids of the Himalayan Collisional Belt. Hot Springs National Park is in the Ouachita Mountains, while the Marathon Mountains extend into Big Bend National Park. Linville Falls flows over 1.1 billion-year-old gneiss, a high-grade metamorphic rock. The first eruption took place in June and didn't stop until August 4th. This puts you on the rim of the. Geological Setting. The next youngest known are around 30 Ma old. Referred to sometimes as "central" volcanoes, these are centered on a mafic shield . x0limtan5xsin4x. Geological Maps of Afar: 1, Northern Afar (1971); 2, Central and Southern Afar (1975). Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. St. Helens, a composite volcano, rises above the surrounding hills of the Cascade Range. the plate is moving in one continuous direction while. Alayta's VEI (Volcanic Explositivity Index) is 2 and is recognized for its regional fissure eruption, lava flow, and damage on land and property. The Himalaya-Tibet region supplies fresh water for more than one-fifth of the world population, and accounts for a quarter of the global sedimentary budget. The damage took place on the land and and properties. It emphasizes what its, shieldvolcano type looks like and where it, comparesto other regions and the geography. Learning Goals: The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Located on the Italian island of Sicily, Mount Etna is one of the most famous volcanoes in the world the facts that its frequently erupts and has a large number of eruption styles. Because cinder cones are made up almost exclusively of loose fragments, they have very little strength. Shield volcanoes generally hold flat, broad appearances. Iapetus Ocean Opens. Mount Alayta is a shield volcano in the Afar Region of Ethiopia. Wiart P, Oppenheimer C, 2005. It is last known to have erupted in 1996, but may have erupted since then without being detected. Approximately 30 different names exist in the literature to describe this unit; the most frequently found equivalents are "Greater Himalayan Sequence", "Tibetan Slab" and "High Himalayan Crystalline". overseas subsidiaries as well as the headquarters of such multinational, Looking for A Digital Marketing Firm.docx, Command software packages h usage software packages h, 11 These are the rules that must be followed when writing a program a syntax b, Define the Fifth Amendment in your own words.docx, Do not proceed until the instructor is ready to review the exercise solutions, This Way replaces escape when youre leading a group of folks away from danger If, for p cbegin p cend p process p p is the current data item Thats the big picture, Which two components would allow you to accomplish this task Choose two A REST, volume shows an elderly man reading a book 63 According to the introduc tion, for insurance of the insured and the insured holds the benefit of the contract, O governo de Buenos Aires aproveitando se da estada de Bol var no Alto Peru, 903BD2C0-AF6D-4CF7-B58A-35F2646FFF1B.jpeg, Extra credit_ Prep Research Paper - Uzair Khan.docx, Take Test_ Week 5_ Quiz 3 - 19SP BUSN 370 Business Law (01).pdf. (the names of the capitols will appear as you zoom in). -.'{ r qLN}cN "ndl /VqUE.W'FSvHHO:R\45* )=NNqGWkt~;:R After the lecture on volcanoes, speculate on the volcano type, based on size, shape, and composition. The U.S. Geological Survey Hawaii Volcano Observatory (HVO) map shown here, dated January 29, 2015, shows the outline of lava that started flowing northeast from Puu Oo on June 27, 2004 (the June 27th Lava flow, a.k.a. Like continental volcanoes, submarine volcanoes are most common where tectonic plates move towards or away from each other. Size and Shape. You are kidnapped by political-science majors (who are Several nappes, termed the "North Himalayan Nappes",[17] have also been described within this unit. Examples of these ancient passive continental margin layers are found today along the Blue Ridge Parkway and in Great Smoky Mountains National Park. The Ouachita Mountains of western Arkansas and southeastern Oklahoma are a classic example of a soft continental collision. Plate convergence ceased soon after the ocean separating ancient North America from Gondwanaland closed. The Atlantic continues to widen along the Mid-Atlantic Ridge. It is now generally accepted that the metasediments of the HHCS represent the metamorphic equivalents of the sedimentary series forming the base of the overlying "Tethys Himalaya". 5. The Alayta lava field, covered by very fresh lava flows, was erupted from N-S-trending fissures along the east . Support your answer with observations on the major tectonic landforms of the region. In the case of divergent plate boundaries, where plates are spreading away from each other, the rate of plate movement plays an important role in determining the type of volcano that forms and the rate of eruptive activity. Photo by Robert J. Lillie. An example of an LIP is the Columbia River Basalt Group (CRGB), which extends across Washington, Oregon, and Idaho (Figure 4.20). Two historical eruptions that were formerly attributed to Afder actually originated from Alayta.

While most of the oceanic crust was "simply" subducted below the Tibetan block during the northward motion of India, at least three major mechanisms have been put forward, either separately or jointly, to explain what happened, since collision, to the 2500km of "missing continental crust". St. Helens sits above a subduction zone, where one tectonic plate goes below another as they come together. D-D is the line of the cross section showing in the tectonic provinces of the Appalachian Mountains. (5 pts), Now navigate to Volcan Descabezado Chico (-35.58, -70.75), it is best to stay in 3D mode, go directly there by typing in the coordinates in the search bar at the upper left side of the screen, make, sure to put in the negative signs or you will be at the wrong location). The sizes and shapes of typical shield, composite, and cinder-cone volcanoes are compared in Figure 4.9, although, to be fair, Mauna Loa is the largest shield volcano on Earth; all others are smaller. The park thus preserves the westernmost vestiges of the oceanic closure and continental collision found not only in the Appalachians of the U. S. and Canada, but also in widely-separated regions of Africa and northern Europe. [4], This is a picture of what a overlook of the Alayta, Volcano might look like. Acadia National Park is in the northern Appalachians in Maine. CNR-CNRS, 1975. February 27, 2023 By scottish gaelic translator By scottish gaelic translator The geology of the Himalayas is a record of the most dramatic and visible creations of the immense mountain range formed by plate tectonic forces and sculpted by weathering and erosion. Describe the likely tectonic setting of the volcanoes in the region (crust type and motion). While the Hawaii mantle plume has produced a relatively low volume of magma for a very long time (~85 Ma), other mantle plumes are less consistent, and some generate massive volumes of magma over relatively short time periods. In some cases additional feature type, elevation, or location details are provided. 150 Million Years Ago The Piedmont Province contains islands and continental fragments (accreted terranes) that were in the ancient Iapetus Ocean and were caught up in the collision between the continents.
