“…These data indicate that near the Rio Grande, the Trans-Pecos region has thermal characteristics intermediate between those of the craton to the east and the average for the Basin and Range province, especially the Rio Grande rift, to the west. The adjacent craton is characterized by heat-flow values about 1.1 HFU (Herrin and Clark, 1956;Sargent and Bedinger, 1985). J.H.…”

“…J.H. Sass (in Sargent and Bedinger, 1985) determined that the Rio Grande rift in southern New Mexico has a heat flow greater than 2.5 HFU. The intermediate area in the Trans-Pecos region, which includes the major grabens of Salt Basin, Lobo Valley, and the Big Bend area has a heat flow of 1.2-1.5 HFU, although heat flow in the Presidio Bolson area probably is 2.5 HFU or greater, similar to that found by J.H.…”

The Trans-Pecos region of Texas, in the southeasternmost part of the Basin and Range province, is semiarid; precipitation ranges from less than 250 to 450 millimeters and potential evapotranspiration is as great as 2.5 meters annually. Structurally, the region is transitional with the Great Plains to the east; only the northern and western parts of the region have well-developed, northwest-trending basins and ranges. The area has experienced repeated deformation since the Precambrian with igneous activity and basin-and-range extension, and to a lesser extent Laramide structures, dominating the topography. Potential host media for isolation of high-level radioactive waste in the region include: (1) Intrusive rocks occurring as stocks, sills, and laccoliths of several rock types; (2) tuffaceous rocks, which include densely welded ash-flow tuff; (3) basaltic lava flows; and (4) argillaceous Manuscript approved for publication, January 3, 1985. rocks. Quaternary tectonism of the region is characterized by: (1) Many small earthquakes and only one damaging earthquake; (2) heat flow that is transitional between that of the craton to the east and the greater heat flow of the Basin and Range; and (3) Quaternary fault scarps, which are more common in the western part of the region. Longterm (late Cenozoic to modern) vertical crustal movement is estimated to be 1 to 2 meters per 10,000 years. Surface and groundwater drainage in the region is to the Rio Grande and to topographically closed basins. Groundwater recharge in the upland areas and in channels of ephemeral streams probably averages about 10 millimeters or less annually. Relatively long travel paths and traveltimes exist from groundwater divides to natural discharge areas. Ground water generally contains less than 1,000 milligrams per liter of dissolved solids except in the Salt Basin where concentrations exceed 3,000 milligrams per liter. Mineral production from the Trans-Pecos region has been dominated by silver, fluorspar, and mercury. Bl B2

“…This work is a part of the U.S. Geological Survey's program for geologic and hydrologic evaluation of the Basin and Range province to identify prospective regions for further study relative to isolation of high-level nuclear waste (Bedinger, Sargent, and Reed, 1984) . This map on the Tertiary basaltic rocks of northern California was prepared from published geologic maps and reports, utilizing the project guidelines defined in Sargent and Bedinger (1984). The map shows the known occurrences of Tertiary basaltic rocks.…”
