Cretaceous rocks in the Southern High Plains, traditionally considered to be part of the High Plains aquifer and recharged by the overlying Ogallala aquifer, actually contain three aquifers with different recharge sources.

The manner in which sedimentary overburden accumulates significantly influences the growth of syndepositional salt structures.

Middle-upper Miocene depositional sequences of offshore Texas represent the last regionally significant influx of terrigenous elastic sediments into the western Gulf Coast Basin.

In the Rio Grande Embayment of South Texas, the Carrizo Formation (lower Eocene) consists of two sand-rich fluvial depositional systems that grade basinward into several deltaic complexes within the upper part of the Wilcox Group.

Barbers Hill salt dome, located in the Texas Coastal Plain near Houston, has a long history of resource exploitation, including oil and brine production, storage of hydrocarbons in solution-mined caverns within the salt stock, and disposal of brine into the cap rock.
