This study documents two upper Paleozoic tectonic unconformities within the Central Pequop Mountains (CPM) in northeastern Nevada. The two unconformities record tectonisim during the interval between the classic Antler orogeny (Late Devonian- Early Mississippian) and the Sonoma orogeny (latest Permian-earliest Triassic) of the western U.S. In the CPM, the stratigraphic succession is comprised ...Description . Near Bowman Lake, the greenschist facies Carboniferous Peale chert forms a moderately E-dipping, NW-trending homocline that is the record of the transition from the Devonian and Early Mississippian Antler Orogeny to the Permian and Triassic Sonoman Orogeny. The Antler Orogeny began began in the late Devonian and continued into the Carboniferous. See also orogeny. Anticline. A layer of rock folded (bent) along an axis, concave side down (i.e., in an upside down "U" or "V" shape). Thus rocks at the center of the anticline, along the fold (crest), are lifted up relative to the rest of the layer. ...

Deer incorporate both physical and behavioral adaptations for survival. Physical adaptations are in their fur, senses, antlers, hooves and stomachs. Deer also exhibit behavioral adaptations in communication.About 1.5 billion years ago, the Dillon area. was near the southern shore of an inland. sea called the Belt Basin (see below). The. sea occupied a depression formed by. crustal extension and it ...The most recent compressional event to affect the Cordillera of North America was the Laramide orogeny, which occurred during the Late Cretaceous to Early Eocene periods.This event resulted in the formation of many mountain ranges, including the Rocky Mountains, due to deformation and uplift of the Earth's crust. The Laramide orogeny was characterized by eastward thrusting and folding of the ...Antler Orogeny. During the Late Devonian and into the early Mississippian, the passive western margin of Laurentia was affected by a collisional tectonic event called the Antler Orogeny. Paleozoic fauna. The Middle Paleozoic seas were dominated by animals that are collectively called the Paleozoic fauna.Pennsylvanian (IP) and Permian (P) deposits (Etchart Formation) and structures in the northern Osgood Mountains and Dry Hills are identified and interpreted to reconstruct a late Paleozoic tectonic history for the time between the Antler and Sonoma orogenies. Mapping, field observations, fusulinid-based unit ages, and structural analysis are used to identify three fold and fault sets, a fault ...

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. ….

An episode of mountain building (the Antler Orogeny) occurred toward the end of the Devonian and continued into the early part of the Carboniferous. By the Permian, sea level had dropped and parts of Nevada were dry land. Plant fossils can be found in rocks formed in shallow lagoons and beaches in the eastern part of the state, while scattered ...events, the Mississippian Antler orogeny and Permian-Triassic Sonoma orogeny, emplaced slope and basinal rocks eastward over the shelf edge in central and western Nevada (Fig. 1B; e.g., Speed and Sleep, 1982; Dickinson, 2000). In eastern Nevada and western Utah, shallow-marine deposition on the continental shelf con-Orogeny' became common in the geological literature. Although the term was used in a purely geographical sense by some authors, we think that Evans & Stubblefield (1929) were the first British geologists to refer to the Caledonian Orogeny as a mountain building event, defined both chronologically and geographically.

Alleghenian Orogeny Grenville Orogeny Antler Orogeny Caledonian Orogeny. Caledonian Orogeny. The spread of land plants likely had which of the following effects? Diversification of land vertebrates Decrease of braided streams Increased soil formation and soil profilesThe Antler orogeny model proposes that cycles of shallow burial and near-surface emergence of the Middle Devonian barrier reef during Late Devonian resulted in parallel dissolution trends by circulation of meteoric groundwaters as shallow aquifers (Kyle 1981; Krebs and Macqueen 1984). A major stage of karstification occurred when the barrier ...

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.
