African Rift Valley. From left to right: Lake Upemba, Lake Mweru, Lake Tanganyika (largest), and Lake Rukwa. A rift valley near Quilotoa, Ecuador. The Ottawa-Bonnechere Graben Þingvallavatn. A rift valley is a linear shaped lowland between several highlands or mountain ranges produced by the action of a geologic rift.
NASA satellite photo of typical Basin and Range topography across central Nevada. The Basin and Range Province includes much of western North America.In the United States, it is bordered on the west by the eastern fault scarp of the Sierra Nevada and spans over 500 miles (800 km) to its eastern border marked by the Wasatch Fault, the Colorado Plateau and the Rio Grande Rift.
The Rio Grande follows this rift for much of its course. The Rio Grande rift is a north-trending continental rift zone. It separates the Colorado Plateau in the west from the interior of the North American craton on the east. [1] The rift extends from central Colorado in the north to the state of Chihuahua, Mexico, in the south. [2]
Texas has been the leading state in petroleum production since discovery of the Spindletop oil field in 1901. [11] As of October 2017, the State of Texas (if treated as its own nation) is the 7th largest oil producing nation in the world, with production totaling approximately 3.78 million barrels (600 thousand cubic meters ) per day of oil ...
The half grabens may have alternating polarities along the rift axis, dividing the rift valley into segments. [ 4 ] Intracontinental and marine rift basins such as the Gulf of Suez , East African Rift , Rio Grande rift system and the North Sea often contain a series of half-graben sub-basins, with the polarity of the dominant fault system ...
The Lower Rio Grande Valley (Spanish: Valle del Río Grande), commonly known as the Rio Grande Valley of South Texas or locally as the Valley or RGV, is a region spanning the border of Texas and Mexico located in a floodplain of the Rio Grande near its mouth. [1]
The rift itself extends from Colorado in the north to Chihuahua in the south, where the river no longer flows. The valley is therefore also a rift valley. [6] Before the Ancestral Rio Grande was integrated into a single watercourse, the valley was a series of closed bolsons each draining into a central playa. [7]
Continental-continental divergent/constructive boundary Oceanic divergent boundary: mid-ocean ridge (cross-section/cut-away view). In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
