	RESEARCH WITHIN THE ANTLER OROGENIC REGION
		The Antler Orogeny was named by Ralph J. Roberts in 1949 (Roberts, 2002) from exposures at Antler Peak, Battle Mountain, Nevada and the tenets are largely a construct of USGS geologists mapping in central Nevada.
		The Antler Orogenic belt consists of a structural complex of lower Paleozoic continental-margin, slope and rise sedimentary and volcanic rocks which were transported, deformed, uplifted, eroded, and overlapped by upper Paleozoic orogenic shed and shallow water carbonates and clastics.
		In the Osgood Mountains, the Adam Peak allochthon is a composite terrane composed of the lower Paleozoic Osgood terrane of Madden-McGuire and Marsh (1991), unconformably overlain by the upper Paleozoic Antler overlap sequence, and the upper Paleozoic Eden Valley terrane of McCollum and McCollum (1989, 1991).

	Orogeny Totally Explained
		Orogeny (Greek for "mountain generating") is the process of mountain building, and may be studied as a tectonic structural event, as a geographical event and a chronological event, in that orogenic events cause distinctive structural phenomena and related tectonic activity, affect certain regions of rocks and crust and happen within a time frame.
		Orogenic events occur solely as a result of the processes of plate tectonics; the problems which were investigated and resolved by the study of orogenesis contributed greatly to the theory of plate tectonics, coupled with study of flora and fauna, geography and mid ocean ridges in the 1950s and 1960s.
		It was, in the context of orogeny, contested hotly by proponents of vertical movements in the crust (similar to tephrotectonics), or convection within the asthenosphere or mantle (geology).

	geology
		The record of the Antler Orogeny is marked by the preserved Devonian Temple Butte Limestone, and the overlying shallow marine and occasional coastal deposits.
		The major effects of the Antler Orogeny were regional metamorphism and large-scale thrust-faulting, during which a thin mass composed of slivers of simatic, ocean crustal rocks and associated deep water sediments was thrust more than 100 km eastward onto the edge of continental margin.
		No magmatic activity occurred within Antler orogeny and it apparently produced neither a major mountain belt nor an extensive detrital wedge, but this orogeny had greater significance to the later history of the Northern American Cordillera.

		Orogeny was used by Gressly (1840) and Thurmann (1854) as orogenic in terms of the creation of mountain elevations, as the term mountain building was still used to describe the processes.
		It was, in the context of orogeny, contested hotly by proponents of vertical movements in the crust (similar to tephrotectonics), or convection within the asthenosphere or mantle (geology).
		In terms of recognising orogeny as an event, Leopold von Buch (1855) recognised that orogenies could be placed in time by bracketing between the youngest deformed rock and the oldest undeformed rock, a principle which is still in use today, though commonly investigated by geochronology using radiometric dating.

	Antler orogeny - Wikipedia, the free encyclopedia
		The Antler orogeny is a mountain-building episode that is named for Antler Peak, at Battle Mountain, Nevada.
		In the late Devonian, the Antler volcanic island arc, approaching the west coast of North America, which was a passive margin with deep embayments, river deltas and estuaries, in today's Idaho and Nevada, finally reached the steep slope of the continental shelf and began to uplift deep water deposits [1].
		It is broadly contemporary with the Acadian orogeny of eastern North America.

		The dates in this figure are old, and though we do not need to know the exact numbers right now, it is important to think about the different forms of geologic evidence available for constraining when certain events happened.
		Note that deposition continues in the Havallah basin east of the arc and west of the developing Antler Mountain belt.

	Abstract (Site not responding. Last check: )
		Analysis of fold and fault types in the Inyo Mountains of Eastern California reveals that the polyphase shortening of the area resulted from the Antler and Sonoma Orogenies and the later Sierran Arc tectonism.
		Northeast-southwest striking folds and faults are consistent with those characteristic of the Devonian Antler Orogeny and the Late Permian-Early Triassic Sonoma Orogeny.
		This geological time placement of the northeast-southwest striking fold and faults is consistent with previous research indicating an eastern Antler and Sonoma boundary within California, while the northwest-southeast striking faults exhibit effects of Mesozoic exotic terrain accretion felt to the east.

		After the Antler orogeny, which would have raised the compressed lands, they underwent extension, which caused them to sink and to become buried under accumulating marine sediments.
		As before, the orogeny was due to a chain of volcanic islands being thrust eastward.
		During each orogeny North America proper grew slightly westward as masses of crustal rocks were compressed and metamorphosed and then became accreted terranes.

		An orogeny is a major cycle of mountain building that affects an entire region of a continent.
		Evidence of these orogenies is seen in the cores of some of the Rocky Mountain ranges, where uplift and erosion have revealed the basement of the crust.
		The largest and most widespread of these Paleozoic orogenies was the Devonian Antler orogeny, which involved subduction, accretion of one or more island arcs, and widespread folding and thrust faulting.

		Nevada was part of a passive margin sequence with shallow water carbonate build up until the Late Devonian when it was interrupted by the Antler Orogeny, which effected the entire Cordillera from Alaska to South America, according to Chamberlain.
		"The Antler Orogeny created a huge mountain range in central Nevada and a seaway east of Nevada, similar to the Cretaceous seaway that created all the source rocks for Wyoming and Montana," he continued.
		When the Antler Orogeny subsided there was a transgression of Pennsylvanian seas and normal deposition until the Late Cretaceous, when the Sevier Orogeny, another major compressional event, took place, he said.

		During the Antler orogeny, island arc and oceanic crust terranes were thrust against and accreted to the continent on the deep ocean side of the Antler belt, in what is now western Nevada, California, and southwestern Oregon.
		The Antler orogeny ended well before the end of the Paleozoic era and the Antler mountains were largely eroded away by the end of the Mesozoic era that followed.
		With its evidence of subduction and terrane accretion and its inland fold and thrust belt, the Antler orogeny was similar to the orogenies that would develop in the Pacific Northwest on an even larger scale during the Mesozoic era and continue through the Cenozoic era up to the present.

		Kluth (1986) claims that the western margin of North America was in a period of relative quiescence during the late Paleozoic; the Mississippian Antler Orogeny had ceased, and the Mesozoic Sonoma Orogeny had not yet begun.
		The Alleghenian Orogeny that was actively creating the Appalachian Mountains to the east was too far removed for significant deformational stresses to be translated to the Ancestral Rocky region.
		The Ouachita-Marathon Orogeny, on the other hand, involved the progressive east-west suturing of South America-Africa with the southern margin of North America.

		The result was the Late Mississippian HERCYNIAN OROGENY (roughly equivalent to the Allegheny Orogeny of North America, which occurred slightly later - in the Pennsylvanian).
		It was this compression that caused widespread thrust-faulting throughout the Appalachians, resulting in the "valley and ridge" province.
		Most of the underlying structures of the present rocky mountains were the result of the Laramide Orogeny; however, the actual landscape we see today resulted from episodes of uplift and erosion in the later Cenozoic era.

		The Antler event is lagely defined as the beaching of an accretionary prism (Speed and Sleep, 1983) or of back arc basin sediments (Burchfeil and Royden, 1991) on the continental slope and is represented in the Roberts Mountains Allochthon.
		In response to the Antler Orogeny, a deep trough, the Pilot Basin, developed oriented approximately north-south in eastern and northeastern Nevada and the shallow continental shelf of central and western Utah flexed and subsided.
		The Middle Pennsylvanian of the western United States records the onset of a second orogenic episode, the Sonoma Orogeny, which partly reactivated the Antler highlands (Rich, 1977).
