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. ... 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 orogeny was a volcanic island arc that was accreted onto western North America with the subduction direction away from North America. This created a mountain range on the west coast of North American called the Antler highlands and was the first part of building the land in the west that would eventually make most of California ...Image transcriptions Important Paleozoic Orogenies Orogeny Age What collided Taconic Sil.

Most of the evidence for this event is in Nevada but the limits of its reach are unknown. A great volume of conglomeratic deposits of mainly Mississippian age in Nevada and adjacent areas testifies to the existence of an important ...Three Devonian pulses of the Antler orogeny are better documented in the chapter on the Bisoni-McKay area. Here, the first Antler pulse in latest Middle Devonian time is obscured within an ~9 m.y. hiatus enlarged by excavation of the Alamo impact crater. The second Antler pulse is recorded by the ~4 m.y. hiatus produced by the regional ...Along North America's eastern margin, this collision is known as the Alleghenian orogeny, which put the final deformational touches on the Appalachian Mountains. Along the southern margin of North America, the Ouachita-Marathon orogeny created a similar chain of folded mountains, now largely eroded away and buried in sediment.지난 22년 동안 Antler orogeny와 Roberts Range가 판 수렴에 미치는 영향에 대한 수많은 보고서가 다양한 저널에 발표되었으며, 이들의 기본 신조는 널리 받아들여져 여기서는 기존 이론이라고 합니다. 증가하다. 특히 뿔 조산운동과 판구조론을 연관시키려는 초기 노력은 E.M. 무어스에 의해 간략하게 ...Thrusting in the Sevier orogenic belt had virtually ceased by the time the Laramide orogeny began east of the Sevier belt in latest Cretaceous time. Laramide mountains were the result of uplift of great blocks of crystalline basement along nearly vertical, reverse, and steep thrust faults. The Uinta arch, which intersects the Sevier orogenic ...Individual Cordilleran orogenic pulses are defined as the Antler orogeny (∼380-340 Ma), Sonoma (∼270-240 Ma), Nevadan (∼180-140 Ma), Sevier (140-50 Ma), Laramide (70-35 Ma) and the ongoing Cascade and Andean orogenies. Similar to the Appalachian orogenic cycle, the Cordilleran cycle has involved the collision of volcanic arcs ...Antler growth places an enormous demand for mineral on the skeleton (sufficient mineral is needed to enable a 30-kg bone to grow in ∼3 months), and to meet this demand cyclical reversible osteoporosis occurs at other skeletal sites (Bubenik, 1983). This bone loss is greatest in non-weight-bearing bones such as the rib.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 ...Mar 29, 2023 · The Antler orogeny reconsidered and implications for late Paleozoic tectonics of western Laurentia Patricia H.

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 ... The Antler orogeny resulted from late Middle Mississippian sinistral-oblique convergence at this step. 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.The Antler orogeny is a textbook example of a Paleozoic mountain building and crustal shortening event in western North America. A relatively complex geologic history of the type Antler at Battle Mountain, Nevada, is interpreted as distinct thrust plates of Lower Cambrian Scott Canyon Formation, Upper Cambrian Harmony Sandstone, and Ordovician ...66.

That was followed by the even more controversial Sonoma orogeny which may have occurred as late as the early Triassic. Evidence for both the Antler and Sonoma orogenies is only found in Nevada. 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 ...Abstract. 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 ...This disconformity, clearly exposed in 10 mountain ranges, indicates regional uplift and erosion of the western facies assemblage and absence of local deformation. The disconformity represents the Antler orogeny. 66. Rodgers J (1971) The Taconic Orogeny. Geol Soc Am Bull 82:1141–1178. 68.

Along the southern margin of North America, the Ouachita-Marathon orogeny created a similar chain of folded mountains, now largely eroded away and buried in sediment.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. Antler orogeny: A Mediterranean-type orogeny. Burchfiel, B. C. ; Royden, L. H. 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.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.

Deer also exhibit behavioral adaptations in communication.. The orogeny is also sometimes termed the HercLate Cretaceous to Early Paleogene phase of the Cordilleran 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 not characterized by obduction of the Roberts Mountains allochthon; rocks composing the “allochthon” essentially were deposited in situ.
