Beaumont Formation, areas predominantly sand

Age: Pleistocene (0.0117 - 2.588 Ma)

Stratigraphic Name: Beaumont Formation

Description: (from Moore and Wermund, 1993a, 1993b) Yellowish- to brownish-gray, locally reddish orange, v. fine to fine quartz sand, silt, and minor fine gravel, intermixed and interbedded. Includes stream channel, point-bar, cravasse-splay, and natural levee ridge deposits, and clayey fill in abandoned channels. Forms poorly defined meander-belt ridges and pimple mounds aligned approx. normal to coast and 1-2 m higher than surround interdistributary silt and clay. Channel fill is dk-brn to brnish-dark-gray, laminated clay and silt, organic -rich. Includes marine delta-front sand, lagoonal clay, and near-shore marine sand beneath and landward of bays along the coast. Interfingers with the interdistributary facies of Beuamont Fm. and rests disconformably on Lissie Fm. Thickness 3-10 m on outcrop; thickens in southeastward in subsurface to more than 100 m.
