Alluvium

Age: Anthropocene (0 - 0.0117 Ma)

Description: alluvium and low terrace deposits along streams, sand, silt, clay, and gravel. Thickness variable. The unit appears on Geologic Map of Texas on the lagoon side of barrier islands where they represent lagoon and wind-tidal-flat sand and clay. These deposits of clay and silty, clayey fine to v. fine quartz sand and shell sand accumulate on alternately dry and flooded barren flats 0.3 m below to 1 m above mean sea level. Mapped areas include active eolian sand dunes on the landward side of barrier islands.

Lithology: Major:{fine alluvium,coarse alluvium}
