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. The orogeny developed in several phases: 1.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 arcThree 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 ...

the Antler foredeep and continental shelf (fig. 9). To the west, eugeosynclinal sediments consisting of fine-grained, siliceous, clastic rocks, chert, and local basalt (western assemblage) were also deposited in the early Paleozoic (figs. 9 and 10). The Antler orogeny, a Mediterranean type orogeny, took place duringThe Antler orogeny is envisioned as a mechanical system where an incompetent acretionary wedge is emplaced over a highly competent footwall. Dynamics of the Antler contractional belt follow those ... ….

However, recent workers have documented numerous tectonic unconformities within the Late Paleozoic stratigraphicThe Late Devonian and Early Mississippian Antler orogeny was the first major tectonic event to affect the passive margin that transected the evaluation area. It is traced regionally by the Roberts Mountains thrust and its accompanying allochthon. An oceanic tectonic assemblage of Ordovician through Devonian pelagic, turbiditic, and volcanic ...

Mississippian Subperiod, first major subdivision of the Carboniferous Period, lasting from 358.9 to 323.2 million years ago.The Mississippian is characterized by shallow-water limestone deposits occupying the interiors of continents, especially in the Northern Hemisphere. These limestones exhibit a change from calcite-dominated grains and …The Alleghenian Orogeny that was actively creating the Appalachian Mountains to the east was too far removed for significant deformational stresses to be translated to the Ancestral Rocky region. The Ouachita-Marathon Orogeny, on the other hand, involved the progressive east-west suturing of South America-Africa with the southern margin of ...
