Circular —Guidebook to Rio Grande rift in New Mexico Compiled by J. W. Hawley, , reprinted , pp., 4 tables, figs., 2 sheets. Discusses the details of geologic features along the rift zone. Included are short papers on topics relative to the overall region. 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).

Published by the American Geophysical Union as part of the Special Publications Series. The Rio Grande rift was largely overlooked as a major continental rift until the 's. Geologists in the United States were preoccupied with the much larger Basin and Range province and with the southern Rocky Mountains. Pitiless Rapture by Rift, Valerie and a great selection of related books, art and collectibles available now at The modern Mesilla and Hueco basins are drained by the Rio Grande, the axial river of the Rio Grande rift. The Rio Grande first entered southern New Mexico between 4 and 5 Ma ago (Bachman and Mehnert, ; Repenning and May, ; Chapin, ; Chapin and Cather, ; Leeder et al., b), and during most of the Pliocene it emptied into Lake. 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. The rift extends from central Colorado in the north to the state of Chihuahua, Mexico, in the south. The rift zone consists of four basins that have an average width of 50 kilometers. The rift can be observed on location at Rio.
