A suite of granitoid plutons from 374–382 Ma (Rabun, Pink Beds, Looking Glass, Mt Airy, Stone Mountain) intruded the eastern Blue Ridge of the Carolinas and Georgia, and a suite of anatectic granitoids (Toluca) from 380 Ma ...The Antler orogeny was a volcanic island arc that was accreted onto western North America with the subduction direction away from North America. This created a mountain range on the west coast of North American called the Antler highlands and was the first part of building the land in the west that would eventually make most of California ...The Late Devonian to Early Mississippian Antler orogeny preceded the Sevier. Ordovician through Devonian rocks of western-derived shale and sandstone facies and eastern carbonate shelf facies are unconformably overlain respectively by Pennsylvanian-Permian Wood River and Mississippian Copper Basin Formations. These two sequences are exposed in ...

During the Antler orogeny, deep-water siliciclastic rocks (western assemblage) were thrust eastward over coeval shelf- and slope-facies marine rocks (eastern assemblage) along the Roberts Mountains thrust . A thick, clastic wedge was deposited in front of the thrust belt (Burchfiel et al., 1992). ...

The Antler orogeny was a 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 deposits of mainly Mississippian age in Nevada and adjacent areas testifies to the existence of an important ...Taconic orogeny, first of three mountain-building events forming the Appalachian Mountains in eastern North America, the Acadian and Alleghenian orogenies being the second and third events, respectively. Originally viewed as a single event, the Taconic orogeny is now known to consist of at least.On the wester or Cordilleran margin of Laurentia, a mountain-building cycle called the Antler orogeny occured. What is the Alleganian Orogeny? The culmination of collision and mountain-building along the eastern margin is the Alleghenian orogeny. Continental redbed rocks of the Dunkard series of Permian age mark the end of the Appalachian orogeny.Sonoma Orogeny and the Golconda Thrust. A thick oceanic sequence of Mississippian through Permian chert, limestone, conglomerate, siltstone, shale, lava flows and pyroclastics accumulated in a trough west of the Antler orogenic belt. This tectonic assemblage was emplaced along the Golconda thrust, at least 60 miles (100 km) eastward or inboard ...

The orogeny is commonly attributed to events off the west coast of North America, where the Kula and Farallon Plates were sliding under the North American plate. Most hypotheses propose that oceanic crust was undergoing flat-slab subduction, that is, subduction at a ...Laurasia (/ l ɔː ˈ r eɪ ʒ ə,-ʃ i ə /) was the more northern of two large landmasses that formed part of the Pangaea supercontinent from around ), the other being Gondwana.It separated from Gondwana (beginning in the late Triassic period) during the breakup of Pangaea, drifting farther north after the split and finally broke apart with the opening of the North …The cause of the Antler orogeny, long ascribed to plate convergence, is here attributed to left-lateral north-south strike-slip faulting in northwestern Nevada.Dec 1, 2006 · Miogeoclinal sedimentation was terminated after mid-Paleozoic time by eastward obduction of overthrust subduction complexes forming the Roberts Mountains and Golconda allochthons (Figs. 4 and 5), which were emplaced during the Devonian-Mississippian Antler orogeny and the Permian-Triassic Sonoma orogeny, respectively . Following the Antler orogeny, uplifted parts of the arc, forearc, and accretionary prism (Roberts Mountains allochthon) eroded, cooled, subsided, and were buried as the new continental margin regained isostatic equilibrium (Dickinson, 1981a,b, 2000; Speed and Sleep, 1982; Ingersoll, 1997) (Fig. 4 C and D).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.ANTLER OROGENY Reading: DNAG G-3, Chapter 3 MAIN TOPICS • Structural Regions • Passive Margin • Antler Orogeny • Subsequent Period STRUCTURAL REGIONS ...

New detrital zircon studies in the Pioneer Mountains, east-central Idaho, were conducted to investigate the stratigraphic evidence of this transition and test models for mid-Paleozoic tectonics and paleogeography.During the Late Devonian or Mississippian, the east-facing Antler arc approached the western margin, and collided with the Cordilleran miogeocline (Chapter 11; Fig. 13). There is some evidence that the Antler Orogeny affected areas as far north as British Columbia (Chapter 5). Distal, passive-margin, deep-water deposits were thrust eastward ...The Antler orogeny occurred in the Mississippian passive margin of the sialic North American continent in Nevada and probably in Idaho (Speed and Sleep, 1982). Speed and Sleep (1982) proposed an Arc-continent collision model for the Antler orogeny. Antler Orogeny (Devonian) Today . Mesozoic Tectonics . A) The Triassic . B) The Jurassic .

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 ...Terms in this set (52) Paleozoic history of most continents involves two things. Mountain building along margins. Numerous shallow-water marine transgressions and regressions over interiors controlling sedimentation. Global sea level changes related to plate tectonics and glaciation. Pannotia breaks apart.Eventually it lapped onto the inland margins of the Acadian mountains in the east and the Antler mountains in the west (Nevada). The Caledonian orogeny began before the Acadian and resulted from a collision between Baltica (western Europe, parts of Great Britain, Scandinavia, and Siberia) and the Greenland region of North America ("Old Red" map).APENNINE OROGENY, ITALY The Sonoma orogeny (250 m.y. ago) followed the Antler orogeny, and if most notable for being so similar to the Antler. The Ancestral Rocky Mountains were created by a mysterious orogeny that occurred in between, at about 300 m.y. ago.The Antler Orogeny caused weak to moderate deformation in the western United States (Fig. 7.4). Parts of the Antler Orogen are now buried by younger deposits, so it is difficult to know its true geographic extent, but from the outcrops that have been identified, the Antler Orogen appears to be about 1/10 the size of the Cordilleran Orogen.Mississippian Antler orogeny. We interpret the juxtaposition of basinal rocks and miogeoclinal rocks in the Northern Ritter Range pendant to in-dicate the southwestern limit of the Antler oro-genic belt in the east-central Sierra Nevada. PALEOZOIC STRATIGRAPHY Previous studies grouped all Paleozoic metasedimentary rocks in the Northern RitterTerranes started to collide with the western edge of North America in the Mississippian age (approximately 350 million years ago), causing the Antler orogeny. During the last half of the Mesozoic Era, much of today's California, British Columbia, Oregon, and Washington were added to North America.
