Shaded relief map of the Llano Estacado. 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.
The Edwards Plateau is a geographic region forming the crossroads of Central, South and West Texas, United States.It is named in honor of Haden Edwards. [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 west. [3]
West Texas is often subdivided according to distinct physiographic features. The portion of West Texas that lies west of the Pecos River is often called "Far West Texas" or the "Trans-Pecos", a term introduced in 1887 by geologist Robert T. Hill. [4] The Trans-Pecos lies within the Chihuahuan Desert and is the aridest part of the state.
The Permian Basin covers more than 86,000 square miles (220,000 km 2), [1] and extends across an area approximately 250 miles (400 km) wide and 300 miles (480 km) long. [2] The Texas cities of Midland, Odessa and San Angelo serve as headquarters for some of the oil production activities in the basin.
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. It is the most mountainous and arid portion of the state, and most of its vast area (outside the city of El Paso) is sparsely populated. Among the nine counties in the ...

Exposed and buried parts of Capitan Reef. Blue area shows area once flooded by the Delaware Sea. The Delaware Basin is a geologic depositional and structural basin in West Texas and southern New Mexico, famous for holding large oil fields and for a fossilized reef exposed at the surface.
The Guadalupe Mountains (Spanish: Sierra de Guadalupe) are a mountain range located in West Texas and southeastern New Mexico.The range includes the highest summit in Texas, Guadalupe Peak, 8,751 ft (2,667 m), and the "signature peak" of West Texas, El Capitan, both of which are located within Guadalupe Mountains National Park.
