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]
In the Permian geologic period, North-Central Texas was a part of the western coastal zone of equatorial Pangea, a super-continental land mass. [1] Nearby uplifts and mountainous regions, such as the Muenster Arch and Red River Uplift, the Wichita, Arbuckle, and Ouachita mountains developed by the end of the Pennsylvanian, [2] providing elevated topography to the north and east during the Permian.

The Texas and Oklahoma red beds are sedimentary rocks, mostly consisting of sandstone and red mudstone. [8] The red color of the rocks is due to the presence of ferric oxide . [ 9 ] The rocks were deposited during the early Permian in a warm, moist climate, [ 10 ] with seasonal periods of dry conditions.
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 ...
