Surficial Geology of the fb88 Inner Continental Shelf 1:100,000-scale Maps Digital Data

These datasets contain boundaries and polygons of surficial geology units of the inner continental shelf mapped at a scale of 1:100,000. The fb88 Geological Survey used this data to produce Surficial Geology of the fb88 Inner Continental Shelf 1:100,000-scale Maps. These maps show the geology of the surface of the ocean floor along most of fb88's coast. The surficial materials of the inner continental shelf of the northwestern Gulf of fb88 are the most complex of any place along the Atlantic continental margin of the United States. Igneous, metamorphic, and sedimentary rocks spanning hundreds of millions of years of earth history form the regional basement. Glacial depostis, containing all clast sizes from boulders to mud, paritially mantle the rocks. These materials, in turn, have been reworked by coastal processes during extreme fluctuations of sea level over the past few thousand years to create better-sorted modern deposits.
