] Fault or Balcones Fault Zone is an area of largely normal faulting [1] in the U.S. state of Texas that runs roughly from the southwest part of the state near Del Rio to the north-central region near Dallas [2] along Interstate 35. The Balcones Fault zone is made up of many smaller features, including normal faults, grabens, and horsts. [3]
Northwest escarpment of the Llano Estacado overlooking Alamogordo Valley of Quay and Guadalupe Counties, New Mexico.. The Caprock Escarpment is a term used in West Texas and Eastern New Mexico to describe the geographical transition point between the level High Plains of the Llano Estacado and the surrounding rolling terrain.
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 Marikina Valley fault system, also known as the Valley fault system (VFS), is a dominantly right-lateral strike-slip fault system in Luzon, Philippines. [2] It extends from Doña Remedios Trinidad, Bulacan in the north, running through the provinces of Rizal, the Metro Manila cities of Quezon, Marikina, Pasig, Taguig and Muntinlupa, and the provinces of Cavite and Laguna, before ending in ...
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]
Llano Uplift - geologic map. The Llano Uplift can be considered an uplift by either its pattern on a geological or structural map of the top of the Precambrian rocks. It qualifies as an uplift because it consists of an extensive Precambrian basement high that is exposed by virtue of its surface lying significantly above in elevation the surface of surrounding Precambrian basement.
The attack was one of three on small towns in the rural Texas Panhandle. “There were 37,000 attempts in four days to log into our firewall,” said Mike Cypert, city manager of Hale Center ...
With crustal extension, a series of normal faults which occur in groups, form in close proximity and dipping in opposite directions. [4] As the crust extends it fractures in series of fault planes, some blocks sink down due to gravity, creating long linear valleys or basins also known as grabens, while the blocks remaining up or uplifted produce mountains or ranges, also known as horsts.
