The δ13C excursion reaches +7.1‰ in the upper part of the Joana Limestone in southeast Nevada and correlates with peaks recognized in Europe and elsewhere in North America. This isotopic shift, one of the largest known Phanerozoic δ13C events, is found within the upper part of theNorth 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.

Mountain-building event that occurred when the part of Gondwana that is now Africa began to collide with Laurasia during the Late Pennsylvanian.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 Antler orogeny occurred in Mississippian time at a passive margin of the sialic North American continent in Nevada and probably in Idaho. Its principal events were the emplacement of an extensive allochthon of oceanic rocks on the continental shelf, subsidence of an elongate foreland basin, and maintenance of highlands in the interior region of the allochthon during and after subsidence of ...cluding the middle Paleozoic Antler and Humboldt orogenies, Permian-Triassic Sonoma orogeny, Jurassic Nevadan and Elko orogenies, and Cretaceous-Tertiary Sevier and LaramideIn 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 ...During the Mississippian period (around 340 million years ago), an island arc collided with and accreted to that coast, generating a major mountain-building event: the Antler Orogeny (Figure 1.10). This orogeny was the first in a long series of mountain-building events that affected the margin of western North America.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. 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. Sonoma Orogeny and the Golconda Thrust. A thick oceanic sequence of Mississippian through Permian chert, limestone, conglomerate, siltstone, shale, lava flows and pyroclastics accumulated in a trough west of the Antler orogenic belt. This tectonic assemblage was emplaced along the Golconda thrust, at least 60 miles (100 km) eastward or inboard ...The first two phases, associated with compressive movements of the Antler orogeny of Nevada, occurred between mid-Frasnian and mid-Osagean time.

Select one: a. Sauk b.The Acadian orogeny is a long-lasting mountain building event which began in the Middle Devonian, reaching a climax in the early Late Devonian. [1] It was active for approximately 50 million years, beginning roughly around 375 million years ago, with deformational, plutonic, and metamorphic events extending into the Early Mississippian. [2]During Late Devonian through Middle Mississippian time, eastward-directed compressional tectonism associated with the Antler orogeny resulted in regional scale folding and imbricate thrusting of the western eugeoclinal assemblage of predominantly siliciclastic rocks, over the eastern autochthonous assemblage of silty carbonate rocks (Roberts et ...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 ...This phase of miogeoclinal development was brought to a close by the Late Devonian-Early Mississippian Antler orogeny, during the final phase of which oceanic rocks were emplaced onto the ...They pro- tically high value. posed that this isotopic anomaly might correlate with the Antler Only in the thick, mostly pelitic, foredeep deposits of the Dale orogeny, development of the Antler foreland, and sequestration of or- Canyon Formation, which forms the bulk of the Diamond Range se- ganic carbon in the sedimentary fill of this foreland.About 1.5 billion years ago, the Dillon area. was near the southern shore of an inland. sea called the Belt Basin (see below).

So Antler Orogeny becomes no.3 and Acadian Orogeny becomes no.4. Therefore, the table should look as below:Late Paleozoic regional unconformities that record tectonic disruptions have been recognized in the foreland of central and eastern Nevada and locally within the Roberts Mountains allochthon; these identify multiple, regional tectonic events between the Devonian-Mississippian initiation of the Antler orogeny and the Permian-Triassic Sonoma ...eny overprinted the Antler orogenic and Pennsylvanian structures (Trexler and others, 2004; Dickinson, 2006). During the Sonoma orogeny, the Golconda allochthon was emplaced via the Golconda and associated thrusts, overlapping the western Antler allochthon. This emplace-ment was a consequence of compression as Permian arcThe Sonoma orogeny resembled the Antler orogeny in terms of overall tectonic process; however, the former differed in the following ways: (1) Sonomia was a larger landmass, (2) the North American margin was more complex prior to collision, including a residual Antler orogen, (3) ...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.

Slope-and-rise sedimentary rocks and seafloor mafic volcanic rocks were thrust upon coeval, shallow ...The Antler Orogeny: The Antler orogeny occurred during the late Devonian period of the Paleozoic era. A small orogeny, it extends roughly from the border of Nevada with California, across the state of Nevada, and into the state of Idaho. Answer and Explanation: 1.The Antler Orogeny was the result of this island arc collision. The extent of this initial orogenic event of western Euramerica is unknown because both the north and south margins have been removed or obliterated by younger tectonic processes.

This then explains that this overthurst material was 'indigenous' (or contiguous with the footwall rock) rather than 'exotic' as the island arcs are.Looking for Antler orogeny?

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.They propose a two-phase history for the antler orogeny: (1) collision of the western edge of North America with the Antler allochthon and downwarping of the continental margin (360-350 Ma), which resulted in deposition of the Diamond Range submarine-fan system; and (2) uplift and low-amplitude folding of the basin (350-320 Ma), accompanied by ...The Late Devonian was a time of continental plate convergence, with enhanced regional subduction-related arc volcanism and large-scale mountain building, such as the Antler orogeny in western Laurentia, the Ellesmerian orogeny in northern Laurentia, the Appalachian orogeny in eastern Laurentia, the Variscan orogeny in southern Laurentia and ...Saamian orogeny - Formation of an extensive area of tonalitic-trondhjemitic crust in Fennoscandia, (3.1-2.9 Ga); Lopian orogeny - Archean orogeny - Formation of two different types of terrain compatible with plate tectonic concepts.One is a belt of high-grade gneisses formed in a regime of strong mobility, while the other is a region of granitoid intrusions and greenstone belts ...Ketner, K.B., 2013, Stratigraphy of lower to middle Paleozoic rocks of northern Nevada and the Antler orogeny: U.S. Geological Survey Professional Paper 1799, 23 p., https://pubs.usgs.gov/pp/1799/.
