Antler orogeny
These are interpreted as early manifestations of the Antler Orogeny, which is well documented in the western United States. Middle Devonian foreland basin strata include the Mount Forster Formation and correlative strata, which change laterally from > 500 m of lithic sandstones, conglomerates and volcanic flows in westernmost exposures to ...Jun 18, 2012 · The Antler orogeny was not characterized by obduction of the Roberts Mountains allochthon; rocks composing the "allochthon" essentially were deposited in situ. Instead, the orogeny was characterized by appearance of an elongate north-northeast-trending uplift through central Nevada and by two parallel flanking depressions.

Antler orogeny, a mountain-building event in Late Devonian and Mississippian time (about 340 to 370 million years ago) that affected a linear belt in the Cordilleran Geosyncline, extending from the California–Nevada border northward through the central part of Nevada into Idaho.

On Hawaii, lava from craters and fissures flow toward the sea by flowing (1) across the top of the land and (2) through lava __________ that occur below the rapidly cooling lava surface. false.Antler orogeny left an apparent structural division . that bisects the northern Basin and Range province . into two roughly symmetric sub-provinces (e.g., Eaton et al., 1978).
In the late Devonian through late Mississippian, the Antler orogeny affected the western margin of the North American plate (Carpenter et al., 1994; Dickinson, 2006). This contractional orogeny produced the Roberts Mountains thrust (Fig. 2) that juxtaposes the Ordovician Vinini Formation and some Mississippian clastic rocks over Devonian ...Earliest stage dissolution trends, coinciding with the Antler orogeny, developed as early as the Late Devonian but were more prevalent during the Carboniferous across southern Saskatchewan and only to a lesser extend across northern Alberta.

Paleozoic History of the Antler Foreland The western edge of Paleozoic North Amer-ica is thought to have been a passive margin until the Late Devonian–Early Mississippian Antler orogeny (e.g., Roberts et al., 1958; Burchfiel and Davis, 1972, 1975).

Following this orogeny, during the Carboniferous Period in the Mississippian epoch 362-320 Ma the Williston Basin again subsided and the area of the Phanerozoic basin was again mainly under tropical marine water.The Antler orogeny produced a thrust fault in central and northern Nevada, the Roberts Mountains thrust. 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.
great plains natural resources During Late Devonian through Middle Mississippian time, eastward-directed compressional tectonism associated with the Antler orogeny resulted in regional scale folding and imbricate thrusting of the western eugeoclinal assemblage of predominantly siliciclastic rocks, over the eastern autochthonous assemblage of silty carbonate rocks (Roberts et ...1996) suggest that the Antler orogeny might. have lasted longer than previously thought— ... santander bank my accountcreating an annual budget Answer: The orogenic events that occurred during the development of Cordillera in Western North America (from oldest to youngest) are Antler Orogeny, formation of Ancestral Rocky Mountains in Colorado associated with Ouachita-Marathon Orogeny, Sonoma ….

That was followed by the even more controversial Sonoma orogeny which may have occurred as late as the early Triassic.Smith et al. (1993) postulated, however, that the Antler orogen of central Nevada and southern Idaho extended to the north, and that the Late Devonian and Mississippian extensional setting in the Canadian Cordillera is the expression of “foreland flexural extension” east of the advancing orogen. precision garage doors pinellas county Mississippian Antler orogeny.
