This 1:1,000,000 scale map shows salt dome locations and salt bed structure in onshore Texas. The GeMS GIS database contains structure contours for both domes and bedded salt.  Source data include structure contour maps between scales of 1:2,000 and 1:24,000 published between 1925 and 2021.

Damon Mound salt dome, located in Brazoria County, Texas, is a shallow diaper that has salt less than 600 ft (180 m) and cap rock less than 100 ft (30 m) below the surface.

Surficial geologic investigations at Palestine, Keechi, and Oakwood salt domes have provided information necessary for evaluating these domes as nuclear waste repositories. Diapir growth uplifted sediments to form domes and created complex radial faulting.

Mobilization of the Louann Salt created the present structural configuration in the central part of the East Texas Basin and was the major control on hydrocarbon accumulation in the area. Salt-cored anticlines, turtle-structure anticlines, and salt diapirs were produced by flow of salt.
