Geologic Setting and Geochemistry of Thermal Water and Geothermal Assessment, Trans-Pecos Texas: with Tectonic Map of the Rio Grande Area, Trans-Pecos Texas and Adjacent Mexico

Hot springs and wells in West Texas and adjacent Mexico are manifestations of active convective geothermal systems concentrated in a zone along the Rio Grande between the Quitman Mountains and Big Bend National Park. Maximum temperatures are 47OC and 7 2 ' ~fo r hot springs and wells in Texas and 9 0 ' ~fo r hot springs in Mexico within 5 km of the border. The area lies along the eastern margin of the Basin and Range province in what may be an extension of the Rio Grande Rift. The heat source for the thermal waters is deep circulation of ground water in an area of relatively high thermal gradient. Recent volcanism is not a source of heat because, based on both paleontologic and isotopic evidence, the youngest observed igneous activity in West Texas is Miocene.
