This folded transparent map is at the same scale as its corresponding Geologic Atlas of Texas (GAT) sheet and can be superimposed on it to compare gravity information with surface geology.

Geologic map that depicts surface geology of Crosby, Dickens, and King Counties and parts of Hale, Floyd, Motley, Cottle, King, Lubbock, Lynn, Garza, Kent, and Stonewall Counties. The Lubbock Sheet honors the late Dr.

Integrated, detailed, and comprehensive study of the physical stratigraphy, tectonic history, hydrogeology, geomorphology, and resource potential of the Palo Duro and Dalhart Basins, Texas Panhandle, is part of a national evaluation of ancient salt basins as potential sites for isolation and mana

Pennsylvanian clastic and carbonate strata were deposited in a variety of environments within the Palo Duro Basin. Maximum accumulation (totaling 750 m or 2,400 ft) occurred along a northwest-southeast axis.

Samples collected from 20 geographically widespread wells in the sparsely drilled Palo Duro Basin were analyzed for total organic carbon content (TOC). Highest values of TOC, up to 6.9 percent, occur in Upper Permian San Andres dolomite in the southern part of the basin.

Geological investigations in the Texas Panhandle and eastern New Mexico indicate that regional subsurface dissolution of Permian evaporites has occurred and is an ongoing process.

Although plots of pressure versus depth are useful for understanding the hydrodynamics of ground-water systems, they can be difficult to interpret.

These are 21 Texas county maps made in cooperation with the American Association of Petroleum Geologists and Society of Economic Paleontologists and Mineralogists, issued between 1929 and 1932 and revised in 1937.

The San Angelo Formation is a mid-Permian sandstone and mudstone sequence about 100 feet thick that crops out in North Texas and dips westward into the Midland Basin; it is composed of two superposed members: the basal Duncan Sandstone Member and the overlying Flowerpot Mudstone Member.

Lower Permian (Wolfcampian) strata of the Palo Duro Basin consist of thick, terrigenous clastic and carbonate facies that were deposited in (1) fan-delta, (2) high-constructive delta, (3) carbonate shelf and shelf-margin, and (4) slope and basinal systems.
