Antler orogeny
The Permian-Triassic orogenic event that occurred with the collision of an island arc with the western margin of North America is called the: A) Antler orogeny. B) Cordilleran orogeny. C) Sonoma orogeny. D) Franciscan orogeny. E) Western orogeny.Passive margin sedimentation ended in Late Devonian time when Cambrian through Devonian oceanic rocks of the Roberts Mountains allochthon were thrust onto the continental shelf during the Antler Orogeny, best documented in north-central Nevada. Slope-and-rise sedimentary rocks and seafloor mafic volcanic rocks were thrust upon coeval, shallow ...

The Quachita orogeny tectonic forces affected the southwestern North America. Select one: TrueEvidence for the Acadian Orogeny from 410-380 Ma in the southern and central Appalachian internides is mostly lacking. A suite of granitoid plutons from 374-382 Ma (Rabun, Pink Beds, Looking Glass, Mt Airy, Stone Mountain) intruded the eastern Blue Ridge of the Carolinas and Georgia, and a suite of anatectic granitoids (Toluca) from 380 Ma ...Queenston Delta, Late Ordovician wedge of sediments that spread across an extensive area of northeastern North America and was thickest in New York and Quebec (the Late Ordovician Period occurred from 461 million to 444 million years ago). The Queenston Delta was produced as sediments that were eroded from a rising landmass in the present Appalachian Mountain region.
For over 50 years the Pan African orogeny has been recognized as a Neoproterozoic tectonothermal episode affecting West Africa 800–550 Ma.As such, the Pan African events are similar to the Appalachian orogenic cycle extending from ∼1100 to 250 Ma and the Cordilleran orogenic cycle of 350 Ma to the present.A significant difference is …In the late Devonian through late Mississippian, the Antler orogeny affected the western margin of the North American plate (Carpenter et al., 1994; Dickinson, 2006). This contractional orogeny produced the Roberts Mountains thrust (Fig. 2) that juxtaposes the Ordovician Vinini Formation and some Mississippian clastic rocks over Devonian ...Study with Quizlet and memorize flashcards containing terms like The late _________ extinction amounts to the most catastrophic event that life has ever faced.

It produced deformed rocks, angular …
The cause of the Taconian Orogeny was a collision between two tectonic plates: the ancestral North American plate’s continental leading edge, and another plate of oceanic affinity, now deceased. The oceanic plate was one of the plates that floored the Iapetus Ocean, and as it moved toward the ancestral North American plate, the oceanic ...C - Early Silurian (430 Ma); East Avalonia slides into Baltica to form Shelvian phase of Caledonian orogeny and together, the two elements close on North America; the Ligerian arc fringes East Avalonia to the south. Chukotia is drawn into arcs along northern Canada and the Antler arc approaches the passive margin of western North America.Antler Orogeny (W) Silurian. Ordovician. Taconic Orogeny* (NE) Cambrian.

Continuing oblique convergence produced the subsequent late Paleozoic basins, structures, and unconformities in northern Nevada. The Roberts Mountains allochthon is translated material from farther north emplaced onto the margin.Plate-tectonic setting of North America during the Late Pennsylvanian. By the end of the Silurian and the beginning of the Devonian, Iapetus had closed everywhere. A major tectonic episode, termed the Scandian phase of the Caledonian Orogeny, occurred when Baltica collided with Greenland ( Figure 10).

There is some evidence that the Antler Orogeny affected areas as far north as British Columbia (Chapter 5). Distal, passive-margin, deep-water deposits were thrust eastward ...
