lauren ericksonmath about The Acadian orogeny is a long-lasting mountain building event which began in the Middle Devonian, reaching a climax in the early Late Devonian. [1] It was active for approximately 50 million years, beginning roughly around 375 million years ago, with deformational, plutonic, and metamorphic events extending into the Early Mississippian. [2]The Antler orogeny occurred in Mississippian time at a passive margin of the sialic North American continent in Nevada and probably in Idaho. Its principal events were the emplacement of an extensive allochthon of oceanic rocks on the continental shelf, subsidence of an elongate foreland basin, and maintenance of highlands in the interior region of the allochthon during and after subsidence of ... kirk heinrich By ~350ma, we find sediments overlapping the Antler Orogeny, suggesting that it had been significantly eroded. The dates in this figure are old, and though we do not need to know the exact numbers right now, it is important to think about the different forms of geologic evidence available for constraining when certain events happened.What is the name of the second orogeny that occurred in this mobile belt ?Ange/S:ifcsi R Qtiii £5 0'12 i "i451 B.

You can see that the Arc Volcanism continued throughout the time that the Antler was created.
