About This Publication
This map is one of four 1:24,000-scale maps of the Aransas and Mission rivers/deltas area at Copano Bay, 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 and Lissie Formations. The map of the Woodsboro Quadrangle depicts the geology for parts of the Aransas and Mission River valleys a short distance upstream from where the Aransas and Mission Deltas prograded into Copano Bay during the mid- to late Holocene. The maps illustrate a variety of geologic elements, including (1) floodplain alluvium, (2) valley-margin deposits, (3) levee deposits, (4) crevasse-splay deposits, (5) abandoned-channel deposits, (6) point-bar deposits, (7) channelbar deposits, (8) terrace alluvium, (9) upper Pleistocene Beaumont Formation deposits with some areas composed of sand-rich channel facies, and (10) Pleistocene Lissie Formation deposits.
