A. Antler orogeny. B. Alleghanian orogeny. C. Himalayan orogeny. D. Sevier orogeny. 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.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 SonomanLate Devonian was a time of the onset of Variscan orogeny. Spreading of the Paleotethys Ocean was the main extensional event. Late Devonian rifting was associated with volcanic activity, especially prominent in the Viluy rift in Siberia. The plate tectonic events could have influenced the extinction of biotas.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 ...Question: During the _ period, subduction caused orogenic activity along the ___ coast of Euramerica, this is commonly referred to as the Antler orogeny.

Antler Orogeny: Antler orogeny began in late Devonian (419 Ma) and spread into Early Pennsylvanian (Upper part of Carboniferous). Great volume of conglomerate beds got deposited during this orogeny. But the most important thing about this orogeny is that, miney williams Sonoma orogeny was originally recognized (Silberling et al., 1962). Therefore, the contact between the Lower Inskip Formation and the Valmy Formation is interpreted to be a portion of the Golconda Thrust, which is considered the basal thrust of the Sonoma orogeny.ANTLER OROGENY. The Antler Orogeny was named by Ralph J. Roberts in 1949 (Roberts, 2002) from exposures at Antler Peak, Battle Mountain, Nevada and the tenets are largely a construct of USGS geologists mapping in central Nevada. The first regional summary of the Antler Orogen appeared almost a decade later (Roberts and others, 1958).Orogeny is a mountain building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges. This involves a series of geological processes collectively called orogenesis.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.
