The region of the present Rio Grande rift and southeastern Colorado Plateau underwent lithospheric extension during middle to late Cenozoic deformation affecting the entire southwestern U.S. Lithospheric mantle was disrupted, and in many regions disp

Results of geological, volcanological, hydrogeochemical, and geophysical field studies conducted in 1988 and 1989 at the Tecuamburro volcano geothermal site in Guatemala indicated that there is a substantial shallow heat source beneath the area of yo

Fracture-filling calcites from GT-2 Drill Core (LASL-DHR Program) yield 87Sr/86Sr ranging from 0.724 to 0.734. These data indicate derivation of Sr in the calcite from 1.7 ± 0.1 b.y. old granitic basement rocks at depth and not from the overlying Ma

Fifty-one lamprophyre dikes of the Navajo volcanic field are randomly oriented in contrast to dikes of similar age from adjacent tectonic provinces. K Ar ages obtained on nine of these dikes indicate that they were emplaced between 28 and 19 m.y. ago

The Phase I prototype hot dry rock (HDR) geothermal system was developed in Precambrian basement rocks at Fenton Hill, New Mexico. Core and cuttings samples from the four deep wells indicate that the reservoir of this Phase I HDR system lies within a

Strontium isotopic analyses of additional samples of the McCartys basalt flow (Holocene) exhibit no evident correlation with distance from the source crater or with strontium content. This confirms our previous comments urging caution in sampling of
