Laramide orogeny The late Cenozoic thrust belts of the Apennine, Carpathian, and Hellenic systems of the Mediterranean region provide modern analogues for the middle Paleozoic Antler orogeny. Each of these young or active mountain belts formed in convergent systems in which thrusting occurred behind a zone of trench retreat, while a region of extension developed contemporaneously within the hanging wall of the ...But to the west the rocks are more siliceous, those coarse conglomerates, and there are some interbedded volcanic rocks. The western rocks are thrust eastward on top of the eastern rocks in the Roberts Mountains Thrust Fault, a major feature which is additional evidence for the tectonic activity we call the Antler Orogeny.The Antler orogeny reactivated basement faults in the craton, most notably the Montana aulacogen, the Cedar Creek fault in eastern Montana, and the Uinta aulacogen.

The same or a related olistostrome is present, but not as spectacu- larly displayed, in two structurally disconnected nearby areas: theWhat caused the Antler orogeny? As outlined in the following paragraphs, plate motion along the western margin of the North American continent in the Late Devonian has been offered as the cause of the orogeny and three varieties of it have been tried—east dipping subduction, west-dipping subduction, and strike-slip motion.By ~350ma, we find sediments overlapping the Antler Orogeny, suggesting that it had been significantly eroded. 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.An orogeny (or orogenic belt) is created when a continental plate is being squeezed; this forces the Earth's lithosphere (crust and uppermost mantle) to cr.The Antler orogeny is a mountain-building episode that is named for Antler Peak, at Battle Mountain, Nevada.

The term and spelling Alleghany orogeny was originally proposed by H.P. Woodward in 1957. The Alleghanian orogeny occurred approximately 325 million to 260 million years ago [1] over at ... The Antler Orogeny, named by geologists in 1951 after Antler Peak on Battle Mountain, was an early orogeny mountain building event in the creation of the Basin and Range Province. The Antler highland, including the Roberts Mountains, formed as fractured deep ocean sediments were thrust upward. North America - Prehistoric, Geology, Plate Tectonics: The interval between about 1.3 billion and 950 million years ago began with continental rifting and culminated in the Grenville orogeny along the southeastern margin of the continent. Northwest-trending dikes were intruded in a short interval of time across the entire northwestern half of the Canadian Shield 1.27 billion years ago. The ... Mississippian Antler orogeny. We interpret the juxtaposition of basinal rocks and miogeoclinal rocks in the Northern Ritter Range pendant to in-dicate the southwestern limit of the Antler oro-genic belt in the east-central Sierra Nevada. PALEOZOIC STRATIGRAPHY Previous studies grouped all Paleozoic metasedimentary rocks in the Northern RitterBy Mid Paleozoic time the western foreland margin began to undergo tectonic changes with a mountain-building event called the Antler Orogeny (Figure 105B). The Antler orogeny impacted the impacted the continental margin region beginning in Late Devonian and continuing into early Pennsylvanian time. The orogeny impacted what is now the Nevada ...Some of the folding in the Roberts Mountains Thrust surface is related to the Antler Orogeny (Daly, et al., 1990). In the northern sections of the Independence Mountains, both allochthonous and autochthonous rocks are unconformably overlain by Carboniferous to Permian sediments of the Overlap Assemblage, which were eroded from the Antler Highland.Jun 18, 2012 · 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 late Devonian and (or) early Mississippian Antler orogeny, and the other during the latest Permian and (or) early Triassic Sonoma orogeny (Roberts and others, 1958; Silberling and Roberts, 1962; Roberts, 1964). The former accreted terrane includes the allochthon of the RobertsSource 5 was likely derived from the clastic wedge of the Antler orogeny. The age distribution of this synthetic source is a close match to that of strata that accumulated on top or adjacent to allochthons of the Antler orogeny in northern Nevada (Fig. 5; Gehrels and Dickinson, 2000). The erratic peaks of the reference curve and mismatch in the ...Sonoma orogeny, an orogenic event that affected the eugeosynclinal (deepwater) portion of the Cordilleran Geosyncline in northwestern Nevada occurring between Middle Permian and Early Triassic times (270 million to 245 million years ago). Evidence for the orogeny consists of an angular unconformity between Late Permian volcanics and older rocks, and a thrust fault, the …Sonoma orogeny. In contrast, an "extensional" Mediterranean- style arc-continent collision, as has been recently proposed for the earlier (middle Paleozoic) Antler orogeny, is probably not an appropriate analogue for the Sonoma orogeny. The weak structural response of the McCloud arc during SonomanThe Antler orogeny is a textbook example of a Paleozoic mountain building and crustal shortening event in western North America.

These thrusts apparently were active during a major episode of Late Triassic arc volcanism, and they constrain the age of the Golconda thrust as pre-latest Triassic.Acadian orogeny, a mountain-building event that affected an area from present-day New York to Newfoundland during the Devonian Period (416 to 359.2 million years ago). Originally a depositional fore-arc basin formed from what was formerly known as the Appalachian Geosyncline; subsequent compressional orogenic activity caused the deposits to be folded as a mountain chain.series of orogeny occurring along the margins of the Pacific Ocean forming the modern Andes Mountains.

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).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 effects of the Antler orogeny on the foreland areas of Montana and Idaho are poorly understood. Therefore this study is important for documenting the stratigraphic record and subsidence history of the foreland and adjacent cratonic platform during Antler convergence. Results from our subsidence analyses allow interpretation of the relative ...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. the Devonian-Mississippian Antler orogeny through the Permian-Triassic Sonoma orogeny and then up to the Sevier orogeny, south-central Nevada was thought to have remained tectonically inactive. However, Pennsylvanian through Jurassic age deformation is documented to the south in Death Valley and to the north. IdentifyingAbstract. We report a large, positive, carbon isotope excursion in the Kinderhookian Stage of the Lower Mississippian in North America and propose that the excursion is linked to the Antler orogeny. The δ 13 C excursion reaches +7.1‰ in the upper part of the Joana Limestone in southeast Nevada and correlates with peaks recognized in Europe ...Accommodation in the Antler Orogeny foreland basin through the Devonian and Carboniferous [Dickinson, 2006] lead to constant accumulation rates during the Middle Carboniferous.
