The Rio Grande rift represents the easternmost manifestation of widespread extension in the western U.S. during the past 35 million years. The rift consists of three major basins and many smaller basins, less than 100 square kilometres (39 sq mi).
Geologic Tour: Rio Grande Rift - New Mexico Bureau of Geology …
The Rio Grande rift is a north-south trending zone of approximately east-west oriented extension that bisects the state of New Mexico. The extension is due to the Colorado Plateau pulling away from the High Plains, which causes the Earth's crust to be stretched and thinned.
The Rio Grande Rift: A Tectonic Reality Shaping Landscapes and …
2020年8月20日 · From Colorado to the Texas Big Bend and Chihuahua, North America is being torn apart – in a tectonic phenomenon geologists call the Rio Grande Rift. The Rift has shaped our region's mountainous landscapes.
The Rio Grande rift is a narrow, north-striking belt of en echelon (slightly overlapping, east or west stepping), elongated basins that bisects southern Colorado and New Mexico. The rift formed when the earth’s crust stretched and thinned during westerly directed extension, starting about 36–37 million years ago.

The Rio Grande rift and Basin and Range Province are two of the most iconic extensional domains on Earth; the Basin and Range Province is the archetypal example of a wide rift, and the neighboring Rio Grande rift is one of the classic modern examples of a narrow continental rift (e.g., Buck, 1991).
Rio Grande Rift FAQ - Utah State University
The Rio Grande Rift began forming between 35 and 29 million years ago when Earth’s lithosphere began to spread apart, triggering volcanism (volcanic activity) in the region. It stretches from the state of Chihuahua, Mexico, to at least Leadville, Colorado (and probably continues further north).
