Geology Of The Dallas–Fort Worth Metroplex
The Dallas–Fort Worth Metroplex sits above Cretaceous-age Stratum, strata ranging from ≈145-66 Ma (million years ago). These Cretaceous-aged sediments lie above the Erosion, eroded Ouachita Mountains and the Fort Worth Basin, which was formed by the Ouachita Orogeny. Going from west to east in the Dallas–Fort Worth metropolitan area, DFW Metroplex and down towards the Gulf of Mexico, the strata get progressively younger. The Cretaceous sediments dip very gently (about 1°) to the east. Structural and tectonic history of the DFW Metroplex The geology of the DFW Metroplex consists of gently tilted sediments of mostly Cretaceous age, which also obscures a much older geologic record. Sediments older than Cretaceous can only be found at the surface in the extreme western part of the DFW Metroplex, in the area around Weatherford, Texas. Ancient folded mountains formed by the Ouachita orogeny existed in the eastern part of the Metroplex 300 million years ago. These ancient mounta ...
