Evidence for the Acadian Orogeny from 410–380 Ma in the southern and central Appalachian internides is mostly lacking. A suite of granitoid plutons from 374–382 Ma (Rabun, Pink Beds, Looking Glass, Mt Airy, Stone Mountain) intruded the eastern Blue Ridge of the Carolinas and Georgia, and a suite of anatectic granitoids (Toluca) from 380 Ma ...Upper plate rocks were thrust eastward over the coeval lower plate rocks during the Late Devonian-Mississippian Antler orogeny (Roberts et al., 1958).

Alleghenian orogeny, mountain-building event, occurring almost entirely within the Permian Period (299 million to 251 million years ago), that created the Appalachian Mountains. The Alleghenian orogeny resulted from the collision of the central and southern Appalachian continental margin of North.Previously, late Paleozoic deformation of the Antler orogen has been referred to as the Humboldt orogeny (Ketner, 1977), and the Humboldt orogeny was envisioned mainly as including late Paleozoic epeirogenic uplift, as well as depression of a number of basins widespread throughout the Cordillera (Snyder and others, 2000).Similar to that of the Antler Orogeny, but accreted a much larger portion of crust to North America. Late Permian to Triassic. Sevier Orogeny. The eastward shift in subduction associated with the Sevier Orogeny led to the formation of another foreland basin; the immense Cretaceous Interior Seaway ultimately developed in this basin. Cretaceous.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.
The Antler orogeny occurred in Mississippian time at a passive margin of the sialic North American continent in Nevada and probably in Idaho.

The Antler orogeny was an enigmatic tectonic event, that began in the early Late Devonian with widespread effects continuing into the Mississippian and early Pennsylvanian. Most of the evidence for this event is in Nevada but the limits of its reach are unknown. A great volume of conglomeratic deposWith the Caledonian orogeny completed Laurussia was delimited thus: The eastern margin were the Barents Shelf and Moscow Platform; the western margin were the western shelves of Laurentia, later affected by the Antler orogeny; the northern margin was the Innuitian-Lomonosov orogeny which marked the collision between Laurussia and the Arctic Craton; 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. IdentifyingThe Antler family name was found in the USA, the UK, and Scotland between 1871 and 1920. The most Antler families were found in USA in 1920. In 1880 there were 10 Antler families living in New York. This was about 77% of all the recorded Antler's in USA. New York had the highest population of Antler families in 1880.The Antler orogeny, a mountain-building event during the Devonian period, is a small orogeny with unusual characteristics. Unlike many orogenies, geologists have not found evidence of metamorphism of the rocks and there is no igneous intrusion into the rock layers.The bulk of this deformation is known as the Ancestral Rocky Mountains orogeny, which consists of several basement uplifts and proximal basins north and northwest of the Ouachita-Marathon suture ...

However, recent workers have documented numerous tectonic unconformities within the Late Paleozoic stratigraphic
A few days ago we talked about the Laramide Orogeny, the brittle breaking of the continental crust into huge uplifts along relatively high-angle faults with miles and miles of throw. And I mentioned a different style of mountain building that took place partially at the same time and in some areas, in the same places.
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.University of OregonThe Appalachian mountain belt formed due to the.

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.
