The Dallas–Fort Worth metroplex is situated in the Texas blackland prairies region, [24] so named for its fertile black soil found especially in the rural areas of ...
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.
Stern is expert on the Geology of the Dallas–Fort Worth Metroplex and the geology of Iran, and has made important contributions to the geology of the Caribbean and the Gulf of Mexico. [citation needed] These studies involve research at sea and on land.
Thin sandstones known as the Templeton Member are found in Grayson County, north of Dallas, that are age equivalent to the lower part of the Turner Park Member. The Templeton Member was originally described as a part of the Woodbine , [ 5 ] but it was recently placed in the Britton Formation of the Eagle Ford Group based on its age as derived ...
It was 1973, and Grapevine Mayor William Tate was 31 and the Metroplex was home to the new Dallas/Fort Worth Airport. Tate boarded a plane with other officials from Tarrant County and took flight.
