Ancient folded mountains formed by the Ouachita orogeny existed in the eastern part of the Metroplex 300 million years ago.

These ancient mountains were reduced by erosion and rifting associated with the opening of the Gulf of Mexico in Jurassic time and were buried beneath younger Cretaceous sediments.

In addition to the displacement of water, an increase in injected magma raised CO₂ levels to around 2-6 times the current level.

Significant deposits of hydrocarbons such as natural gas have economic importance as is seen in formations like the Barnett Shale.

Pangea started to break up during the Triassic ≈225Ma.

A simulated-color satellite image of Dallas and Fort Worth, Texas, taken by NASA's Landsat 7 satellite. The geology of the DFW Metroplex consists of gently tilted sediments of mostly Cretaceous age, which also obscures a much older geologic record.

Dallas makes up much of the right half of the urbanized area. 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.

These billion year old rocks can only be seen several thousand feet in the subsurface by boreholes and other data in the DFW Metroplex.
