About This Publication
This map is one of four 1:24,000-scale maps of the Aransas and Mission deltas area, Texas Gulf of Mexico Coast. This study area lies within modern-to-Holocene Aransas and Mission fluvial-deltaic and bay/estuary settings. Here, the Aransas and Mission river valleys dissect Pleistocene fluvial-deltaic deposits of the Beaumont Formation. The map of the Bayside Quadrangle depicts the geology for the area where the Aransas
delta progrades into the western margin of Copano Bay. Geology of this area partly consists of upland Pleistocene Beaumont clay, silt, sand, and minor gravel of fluvial-deltaic interdistributary and distributary settings. Sand-rich channel facies of the Beaumont Formation are displayed. The area also includes part of the upper Beaumont Formation barrier facies, Ingleside deposits. Modern-to-Holocene delta plain and bay margin deposits and tidal flats are adjacent to Copano Bay.
