Numerical computation of co‐oscillating palaeotides in the Catskill epeiric Sea of eastern North America

摘要: A numerical model describing two-dimensional, shallow water, long wave propagation has provided estimates of the co-oscillating palaeotides in upper Devonian Catskill Sea. This sea was open to ocean along present Gulf Coast and, moving clockwise, circumscribed by Transcontinental Arch, Old Red Sandstone Continent, and rising Appalachian Orogen. Using best basin bathymetry open-ocean tidal range, indicates high mesotidal low macrotidal ranges for Shelf ancestral Appalachians. The Mid-Continent Shelf, centred on Iowa, is considered have been microtidal. These conclusions are not sensitive reasonable variations shelf geometry support hypothesis that at least some epicontinental seas could tide-dominated.
