The surface expression of the fault is the Balcones Escarpment, [7] which forms the eastern boundary of the Texas Hill Country and the western boundary of the Texas Coastal Plain, and consists of cliffs and cliff-like structures. Subterranean features such as Wonder Cave and numerous other smaller caves are found along the fault zone.
Texas is approximately bisected by a series of faults that trend southwest to northeast across the state, from the area of Uvalde to Texarkana.South and east of these faults, the surface exposures consist mostly of Cenozoic sandstone and shale strata that grow progressively younger toward the coast, indicative of a regression that has continued from the late Mesozoic to the present.
The Long Point–Eureka Heights fault system is a system of geologic faults in Houston, Texas.It runs beneath the metropolitan area from the southwest to the northeast. The various faults are characterized as normal faults, meaning that the downthrown side is in the direction of the dip of the fault p
