They have both pre- and post-Antler Orogeny movement recorded, with the most recent displacement being associated with the Tertiary Basin and Range activity (Hays and Foo, 1990). Within the Gold Acres deposit the following sequence has been mapped, from the structurally lowest unit upwards (Hays and Foo, 1990):In contrast, the Eureka district is located east of the Roberts Mountain thrust front within the foreland region of the Antler orogeny (Figure 1; Giles and Dickinson, 1995;Poole and Sandberg, 2015).and propose that the excursion is linked to the Antler orogeny. 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 the

Three orogenies ultimately produced the mountain chain: the Ordovician Taconic orogeny, which involved arc accretion; the Acadian-Neoacadian orogeny, which involved north-to-south, transpressional, zippered, Late Devonian-early Mississippian collision of the Carolina superterrane in the southern-central Appalachians and the Avalon-Gander ...Alleghanian orogeny A phase of mountain building, that began in the Early Carboniferous and was completed by the end of the Permian, caused by the collision between N. America and Africa.It formed part of the general WSW to ENE Hercynian belt. The orogeny affected the Lower Palaeozoic basement and Lower Permian strata along the western margin of the southern and central parts of the ...The Laramide orogeny was caused by subduction of a plate at a shallow angle. The orogeny is commonly attributed to events off the west coast of North America, where the Kula and Farallon Plates were sliding under the North American plate. Most hypotheses propose that oceanic crust was undergoing flat-slab subduction, that is, subduction at a ...In this image we see where early Pennsylvanian sediments were deposited over the eroded interior of the mountains of the Antler Orogeny. This suggests that the topography created by the Antler was eroded to low relief that the Antler Orogeny was complete by the early Pennsylvanian.

These curves show distinct peaks in We suggest that events associated with the Antler orogeny can in part the upper Kinderhookian (middle Tournaisian), which suggests that the shift explain the δ13C excursion observed in the late Kinderhookian. Conodont we recognize in the upper part of the S. isosticha Zone in Nevada (Joana collections from ...Following the Antler orogeny, uplifted parts of the arc, forearc, and accretionary prism (Roberts Mountains allochthon) eroded, cooled, subsided, and were buried as the new continental margin regained isostatic equilibrium (Dickinson, 1981a,b, 2000; Speed and Sleep, 1982; Ingersoll, 1997) (Fig. 4 C and D).

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.
