Petroleum geology and the distribution of conventional crude oil, natural gas, and natural gas liquids, East Texas basin, USGS Open-File Report 88-450K Author R.Q. Foote, L.M. Massingill, and R.H. Wells
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.
The northern end of the Appalachian Basin extends offshore into Lakes Erie and Ontario as far as the United States–Canada border. The province covers an area of about 185,500 square miles (480,000 km 2) and is 1,075 miles (1,730 km) long from northeast to southwest and between 20 and 310 miles (30 and 500 km) wide from northwest to southeast ...
The divisions of regional geology are drawn in different ways, but are usually outlined by a common geologic history, geographic vicinity or political boundaries. The regional geology of North America usually encompasses the geographic regions of Alaska, Canada, Greenland, the continental United States, Mexico, Central America, and the ...
USGS map colored by paleogeological areas and demarcating the sections of the U.S. physiographic regions: Laurentian Upland (area 1), Atlantic Plain (2-3), Appalachian Highlands (4-10), Interior Plains (11-13), Interior Highlands (14-15), Rocky Mountain System (16-19), Intermontane Plateaus (20-22), & Pacific Mountain System (23-25) The legend ...
Shaded relief map of the United States, showing 10 geological provinces. The richly textured landscape of the United States is a product of the dueling forces of plate tectonics, weathering and erosion. Over the 4.5 billion-year history of the Earth, tectonic upheavals and colliding plates have raised great mountain ranges while the forces of ...
