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.
Texas has five minor estuaries interspersed among its seven major estuary systems. These are smaller, less complicated estuaries with less significance to the state's hydrology, ecology, and economy. Several of these are simply the lower tidal reaches of particular rivers, without barrier islands or embayments to separate them from the Gulf of ...
Cretaceous Formations of the Dallas-Fort Worth Metroplex Geologic map and the labeled geologic formations that lie directly beneath the surface in Dallas County Cretaceous formations of Texas Where the DFW Metroplex was located during the last super continent known as Pangea Placement of Tectonic Plates and DFW location around ≈94 million years ago The Cretaceous rocks in the DFW Metroplex ...
Nevertheless, and since ocean basins are interconnected, many oceanographers prefer to refer to one single ocean basin instead of multiple ones. Older references (e.g., Littlehales 1930) [4] consider the oceanic basins to be the complement to the continents, with erosion dominating the latter, and the sediments so derived ending up in the ocean ...
Mid-ocean ridge, also known as Oceanic ridge – Basaltic underwater mountain system formed by plate tectonic spreading; Oceanic trench – Long and narrow depressions of the sea floor; Paleoclimatology – Study of changes in ancient climate; Paleomap – Map of continents and mountain ranges in the past based on plate reconstructions
The unique shape of the Gulf of Mexico, surrounded on all sides by continental crust, is the result of two different tectonic boundaries: an ocean-continent transform boundary, and a magmatic plume fueled seafloor spreading center active contemporaneously in regards to geologic time. The transform boundary caused two approximately 22 ...
Map of the basins, reefs and platforms that make up the Permian Basin in West Texas. The Val Verde Basin is a marginal foreland basin located in West Texas, just southeast of the Midland Basin. The Val Verde is a sub-basin of the larger Permian Basin and is roughly 24–40 km wide by 240 km long. [1]
The Basin and Range province has a characteristic topography that is familiar to anyone who ventures across it. Steep climbs up elongate mountain ranges alternate with long treks across flat, dry deserts. This basic topographic pattern extends from eastern California to central Utah, and from southern Idaho into the state of Sonora in Mexico.
