The Blanco Basin Formation (Eocene), San Juan Mountains region, Colorado and New Mexico

Hydrogeologic framework of the Mesilla Basin in New Mexico and western Texas

“…shallow in comparison to many other rift basins (Chapin, 1988, Lozinsky, 1987, 1388Brister, 1990;Hawley and.Haase, 1992). :Maximum'thickness of upper Cenozoic fill is about 3,000 ft (1900 m).…”

“…been recognized in all major basins of the Rio Grande rift in New Mexico and adjacent parts of Colorado, Texas and Chihuahua. (Spiegel and Baldwin, 1963;King et al, 1971;Hawley, 1978;Seager and Morgan, 1979;Gile et al, 1981;Wilson et al, 1981;Seager et al, 1982Seager et al, , 1987Chapin, 1988;Hearne and Dewey, 1978;Brister, 1990;Gustavson, 1991;Lozinsky and Tedford, 1991). They have been formally defined, however, only in the Albuquerque and Mesilla Basins (Hawley and Haase, 1992; this report).…”

They form the basic building blocks of the conceptual model of this study.…”

“…Geologic investigations of similar basin-and valley-fill sequences elsewhere along the Rio Grande rift furnish much additional information on late Cenozoic depositional environments and geologic history (e.g. Spiegel and Baldwin, 1963;Hawley et al, 1976;Smith et al, 1970;Galusha and Blick, 1971;Chapin and Seager, 1975;Hawley, 1978;Seager and Morgan, 1979;Chamberlin, 1980;Gile et al, 1981;Seager et at., 1982Seager et at., , 1987Love, 1986;Lozinsky, 1987;Chapin, 1988;Brister, 1990;1ngersoll.et al, 1990;Gustavson, 1991;Lozinsky and Tedford, 1991;Lohman et al ., 1991;Smith et al, 1991).…”
