] 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]
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]
Wonder Cave is a show cave located in the Balcones Fault in San Marcos, Texas. Its entrance is one mile southwest of the Hays County Courthouse. The cave is reported to be the only commercially operated dry-formed cave in the United States ("dry-formed" because the fissure was opened not by erosion but by the earthquake that produced the ...
The Mount Bonnell fault has a vertical throw of up to 600 feet, making it the most prominent normal fault within the Balcones Fault Zone. During the Miocene, the Edwards Group was displaced downwards relative to the Glen Rose Formation on the Edwards Plateau, so that they are juxtaposed. [19]
Much of the source water to the Medina River is produced by springs emerging due to the presence of the Balcones Fault. This locale of the Balcones Fault is associated with an important ecological dividing line for species occurrence. For example, species such as the California Fan Palm, Washingtonia filifera, occur only west of the Medina ...
The geology of Medina Valley has been analyzed for some time, [1] with a prominent feature being the Balcones Fault Zone. There are a number of flora and fauna species associated with the Medina Valley. Some of the species in and close to Medina Valley have their distributional range defined by the Medina Valley and/or the Balcones Fault.
These eruptions occurred along a 250 mile long by 50 mile wide belt of submarine volcanoes, which are located in present-day south-central Texas. This belt of volcanoes coincides with the trend of the Balcones Fault zone and is known as the Balcones volcanic province.
The Salado Springs are located in the Balcones Fault zone, and they reach the surface through artesian pressure by way of faults in the Cretaceous Edwards limestone. The main recharge area for the springs is probably several miles to the southwest in Williamson County, where several faults intersect with Salado Creek.
