Geology of Texas. Texas contains a wide variety of geologic settings. The state's stratigraphy has been largely influenced by marine transgressive-regressive cycles during the Phanerozoic, with a lesser but still significant contribution from late Cenozoic tectonic activity, as well as the remnants of a Paleozoic mountain range.

[2] It is bounded by the Balcones Fault to the south and east; the Llano Uplift and the Llano Estacado to the north; and the Pecos River and Chihuahuan Desert to ...
The Red Beds of Texas and Oklahoma are a group of Early Permian -age geologic strata in the southwestern United States cropping out in north-central Texas and south-central Oklahoma. They comprise several stratigraphic groups, including the Clear Fork Group, the Wichita Group, and the Pease River Group. [1] The Red Beds were first explored by ...
Geologic map of Dallas, with Woodbine at left. Woodbine Formation stratigraphic column in Texas. The Woodbine Group is a geological formation in east Texas whose strata date back to the Early to Middle Cenomanian age of the Late Cretaceous. [1] It is the producing formation of the giant East Texas Oil Field (also known as the "Black Giant ...
Llano Uplift. Precambrian and Paleozoic inlier surrounded by Cretaceous uplands. The Llano Uplift is a geologically ancient, low geologic dome that is about 90 miles (140 km) in diameter and located mostly in Llano, Mason, San Saba, Gillespie, and Blanco counties, Texas. It consists of an island-like exposure of Precambrian igneous and ...
Trans-Pecos. The Trans-Pecos, as originally defined in 1887 by the Texas geologist Robert T. Hill, is the distinct portion of Texas that lies west of the Pecos River. [1] The term is considered synonymous with Far West Texas, a subdivision of West Texas. [2] The Trans-Pecos is part of the Chihuahuan Desert, the largest desert in North America.
