dovician marine carbonates is known as the “Great American Bank” (Peters and Gaines 2012). B. Late Paleozoic marine regression 1. Devonian Euramerica region redbeds The Old Red Sandstone of Europe is very similar to the American Catskill redbeds. The Old Red Sandstone is inferred to have formed in a region with early marine regression of a shallow epicontinental sea, associated with the regional Acadian Orogeny (Prothero and Dott 2010). Lower and Middle Paleozoic epeiric seas covered practically all the North American craton except during the Early Devonian regressive episode. The Acadian orogeny was the greatest orogeny for the Appalachian orogenic belt. Much of the craton was above sea level then and was being eroded (Prothero and Dott 2010). The Devonian red clastic wedge deposits of eastern Greenland and northwest Europe, like those of the eastern United States, reflect the rapid erosion of high Acadian mountains. Sediments are inferred to have been transported in both directions away from a single great mountain range (Prothero and Dott 2010). Structurally the two margins of the North Atlantic Ocean are very similar in shape. With the opening of the North Atlantic Ocean, commencing in the Jurassic, these two areas were separated. 2. Mid-Carboniferous a.Global All over the world, most Mississippian deposits are typified by thick sequences of marine limestone (Prothero and Dott 2010). In cratonic Figure 2.
