|
| Western Ecuador consists of a complex tectonic melange of oceanic terranes accreted to the continental margin from Late Cretaceous to Eocene time. |
|
|
|
| These terranes now make up much of southern Europe and parts of eastern North America. |
|
| By this mechanism holes, commonly up to 20m deep and 40m or more across, continue to appear suddenly in gypsiferous terranes throughout the world. |
|
| Rift basins in the Red Sea area developed in terranes accreted in Pan-African time, and it is believed that some of these ancient sutures controlled later Red Sea rifting. |
|
| The gold-producing Witwatersrand beds of South Africa may correspond to the terranes of western Queen Maud Land. |
|
| A useful approach to considering Britain's geological structure is to examine the various terranes from which it is composed. |
|
| At that time, thrust sheets now lying east of the leading edge of the accreted terranes, were emplaced tens of kilometres onto the carbonate continental shelf in a manner similar to that in the Appalachian Orogen. |
|
| Locally, where these terranes are thin or missing the neighbouring Quesnel Terrane in the west is juxtaposed against the Neoproterozoic and younger continental margin assemblages in the east. |
|
| The leading edge of accreted terranes in the Cordillera generally forms the boundary between the Devonian to Triassic oceanic Slide Mountain Terrane and the Neoproterozoic to Triassic pericratonic Kootenay Terrane. |
|
| So-called exotic terranes, geologic fragments that differ markedly in stratigraphy, paleomagnetism, and paleontology from adjoining continental crust, were accreted to the margin of the North American plate. |
|
| Description: The major scientific objective of the project is to understand the processes that led to the final assembly of Gondwanaland-derived terranes in East and South-East Asia. |
|
| The Western Churchill is an extensive Archean and Proterozoic tract of land that contains a number of large magmatic terranes conducive to hosting Ni-Cu-PGE mineralization. |
|
| The reconstruction of original relationships between the arc systems has important implications for the development of the Laurentian margin and for the prospectivity of terranes and distribution of mineral deposits. |
|
| Paleontology takes away a large part of the uncertainty from geological interpretations in Phanerozoic terranes and therefore reduces the element of luck or chance in mineral and hydrocarbon exploration. |
|
| Relics of this process are incorporated into the Cordilleran mountain chain as discrete terranes that were accreted to the continent during or after the Devonian. |
|
| Terranes in the Insular Belt, that in places extend eastward into the Coast Belt, were accreted to the terranes in the Intermontane belt in the mid-Cretaceous, about 100 million years ago. |
|
| As the vice was closed between Wrangellia and terranes to the east, the rocks in the vice were squeezed downwards and upwards, metamorphosed and uplifted. |
|
| The Miramichi and the northern part of the Tobique-Chaleur geologic terranes display favourable geologic settings for graphite as an accessory to various forms of sulphide mineralization. |
|
| He has applied conodonts to solving problems in complex tectonic terranes and has also developed biostratigraphic schemes for many sedimentary basins. |
|
| Fossils in Slide Mountain, Quesnel and Stikine terranes most closely resemble forms that lived on the old continental edge in the southwestern United States. |
|
| Specific studies have been related to the characterization and distribution of terranes, the distribution and offsets of orogen-parallel faults and the relationships of mineral deposits to various tectonic assemblages. |
|
|
|
| It was caused by the closure of the Iapetus Ocean when the continents and terranes of Laurentia, Baltica and Avalonia collided. |
|
| The basin closed when these Caledonian deformed terranes were accreted again to Laurussia during the Hercynian orogeny. |
|
| Individual terranes typically contain suites of structures, the histories and form of which differ from those of neighbouring terranes. |
|
| Similar terranes added to the northern Laurentia, in contrast, have affinities with Baltica, Siberia, and the northern Caledonies. |
|
| It is thought that much of North America west of the Rocky Mountains is composed of such terranes. |
|
| The collage of terranes that forms western North America was mostly in place with the collision of Wrangellia. |

|
| The mountain belt came together as an accretion of terranes. |
|
| Along most of the edges of this craton are fragments of crustal material called terranes, accreted to the craton by tectonic actions over the long span of geologic time. |
|
| The North American Cordillera is an accretionary orogen which grew by the progressive addition of allochthonous terranes along this margin from the Late Palaeozoic. |
