the U.S. is the Late Devonian-early Mississippian Antler orogeny, followed by tectonic quiescence, and ending with the Late Permian-early Triassic Sonoma orogeny (e.g., Burchfiel and Davis, 1975; Dickinson, 1977; Burchfiel et al., 1992). However, recent workers have documented numerous tectonic unconformities within the Late Paleozoic stratigraphicAs used here, the term Antler orogeny signifies only re-gional uplift along the outer miogeocline; it does not imply folding and thrust faulting. Ironically, the tec-tonic event in the vicinity of Antler Peak that is cele-brated as the type occurrence of the Late Devon-ian–Early Mississippian Antler orogeny is probably of Middle Pennsylvanian ...The Antler orogeny resulted from late Middle Mississippian sinistral-oblique convergence at this step.

Parts of the Antler Orogen are now buried by younger deposits, so it is difficult to know its true geographic extent, but from the outcrops that have been identified, the Antler Orogen appears to be about 1/10 the size of the Cordilleran Orogen.Terranes started to collide with the western edge of North America in the Mississippian (approximately 350 million years ago), causing the Antler orogeny. For 270 million years, the effects of plate collisions were focused very near the edge of the North American plate boundary, far to the west of the Rocky Mountain region.The Antler Orogeny and the First Suspect Terrane: Middle Devonian to Late Pennsylvanian: Ca. 400-300 Ma.

Expert Answer.Mississippian rocks of the Antler foreland basin in Nevada (western United States) record its evolution in detail, clarifying the timing and tectonic significance of the Antler orogeny. Synorogenic clastic sediments mark the initiation of tectonism; they arrived in Nevada from the north or northwest in late Early Mississippian (Osagean).The Antler orogeny produced a thrust fault in central and northern Nevada, the Roberts Mountains thrust. This fault placed deep water, western siliceous facies continental rise strata over eastern carbonate facies carbonate rocks, and uplifted the Antler highland, which then shed sediment into a subsiding foreland basin to the east. Eventually it lapped onto the inland margins of the Acadian mountains in the east and the Antler mountains in the west (Nevada). The Caledonian orogeny began before the Acadian and resulted from a collision between Baltica (western Europe, parts of Great Britain, Scandinavia, and Siberia) and the Greenland region of North America ("Old Red" map).The Antler orogeny occurred in Mississippian time at a passive margin of the sialic North American continent in Nevada and probably in Idaho.

Antler orogeny. a Late Devonian to Mississippian episode of mountain building that affected the Cordilleran mobile belt; was caused by subduction, resulting in deep water deposits and oceanic crustal rocks being thrust eastward over shallow water continental shelf sediments, thus closing the narrow ocean basin that seperated the island arc from ...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 …These observations indicated that the Havallah basin did not originate as a simple, post-Antler orogeny rift basin, nor is the Mediterranean model for opening of a basin a solution to the ...The Antler orogeny was a Devonian-Mississippian (375-320 Ma) mountain building event that occurred along the western Laurentian margin. The initiation of the Antler orogeny is marked by the emplacement of the Roberts Mountain Allochthon (RMA) that thrust Cambrian-Devonian deep water marine siliciclastic rocks 100 km eastward onto the western Laurentian margin.Answer: The orogenic events that occurred during the development of Cordillera in Western North America (from oldest to youngest) are Antler Orogeny, formation of Ancestral Rocky Mountains in Colorado associated with Ouachita-Marathon Orogeny, Sonoma …. View the full answer.The Antler Orogeny was a middle to late Paleozoic precursor of the main period of folding and faulting that formed the Cordillera.

The deformation post-dates the Antler orogeny and has been termed the Humboldt orogeny by Ketner (1977). Tan beds in saddle contain fossils that date them as approximating the Lower and Upper Mississippian boundary. The thicker-bedded Diamond Peak strata below (west of) the fossiliferous unit comprise a submarine fanPaleozoic tectonic signal in the western U.S. was latest Devonian formation of the Antler foreland basin (Dickinson et al., 1983) and emplacement of the RMA (Dickinson, 2004; Dickinson, 2009; Domeier & Torsvik, 2014) (Figure 2). The tectonic setting of the Antler orogeny is poorly understood, due to anomalous charac-fined, Late Devonian Antler orogeny or the Permian-Triassic Sonoma orogeny have also been documented elsewhere in Nevada (e.g., Erickson and Marsh, 1974; Silberling et al.,This next image portrays the timing of different depositional events around the time of the Antler Orogeny. You can see that the Arc Volcanism continued throughout the time that the Antler was created. You can also see that the sediment found in the Antler Allochthon were experiencing active deposition until ~360ma. The filling of the foredeep then starts ~355ma, suggesting that the material ...The sequence was subjected to another orogenic event in the late Permian to lower Triassic, the Sonoma Orogeny, which resulted in the further eastward transport of western siliceous rocks over both the eastern carbonate assemblage and the post Antler overlap assemblage. This thrusting was over the Golconda Thrust, the main trace of which ...Taconic orogeny, first of three mountain-building events forming the Appalachian Mountains in eastern North America, the Acadian and Alleghenian orogenies being the second and third events, respectively. Originally viewed as a single event, the Taconic orogeny is now known to consist of at least. The Antler orogeny was not characterized by obduction of the Roberts Mountains allochthon; rocks composing the “allochthon” essentially were deposited in situ. Instead, the orogeny was characterized by appearance of an elongate north-northeast-trending uplift through central Nevada and by two parallel flanking depressions.The complex structural features include (1) a middle to late Paleozoic thrust belt (Antler orogenic belt, Golconda thrust, Sonoma thrust) extending across south -central and northeastern Nevada into south - ... development of the Antler Orogeny in Late Devonian and Early Mississippian time, with folding, faulting, and eastward thrusting of ...Mississippian (Antler orogeny, Roberts et al., 1958; Speed, 1982,1983), and the Permian-Triassic (Sonoma orogeny, Sllberling and Roberts, 1962; Speed, 1979,1982,1983) (Figs. 4,5,12).

The Antler orogeny is a mountain-building episode that is named for Antler Peak, at Battle Mountain, Nevada.The orogeny extensively deformed Paleozoic rocks of the Great Basin in Nevada and western Utah during Late Devonian and Early Mississippian time. In the late Devonian, the Antler volcanic island arc terrane collided with was then the west coast of North America in the ...We interpret that the entire package was tectonically transported south along the western Laurentian margin and then emplaced eastward onto the craton during the Late Devonian-Early Mississippian Antler orogeny.Furthermore, because the magnitude of the ␦ 13 C peak is roughly ϩ1‰ larger in the Antler foreland than it is in the midcontinent, U.S.A.
