Antler orogeny

Orogeny: An orogeny is a geological event responsible for the formation of mountains. Geologists have found evidence of orogenies dating back several billion years, but orogenies are not just a thing of the past.

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 deposThe 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 ...The cause of the Antler orog- eny, long ascribed to plate convergence, is here attributed to left-lateral north-south strike-slip faulting in northwestern Nevada.Earth Sciences questions and answers. 1) The west coast experiences the Antler Orogeny.

These are interpreted as early manifestations of the Antler Orogeny, which is well documented in the western United States.

The Alleghenian orogeny resulted from the collision of the central and southern Appalachian continental margin of North. 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.The Antler orogeny occurred in Mississippian time at a passive margin of the sialic North American continent in Nevada and probably in Idaho.

This fault placed deep water, western siliceous facies continental rise strata over eastern carbonate facies carbonate rocks, and uplifted the Antler highland, which then shed sediment into a subsiding foreland basin to the east. ….

This bone loss is greatest in non-weight-bearing bones such as the rib.The Acadian Orogeny in the Devonian (around 380 m.y. ago) was the result of collision of Europe with northern portions of Laurentia (Greenland and Newfoundland) and added another permanent terrane to the eastern cratonic margin (the Avalon Terrane added portions of New England and Maritime Canada.of crust associated with east-dipping subduction (Antler orogeny) formed a north–south trending foredeep, slope, and platform collectively called the Antler foreland in the United States and the Prophet trough in Canada (Fuentes and others, 2012; Beranek and others, 2016).
