Geological and geochemical reconnaissance in the central Santander Massif, Departments of Santander and Norte de Santander, Colombia
James George Evans
1976, Open-File Report 77-281
The central Santander Massif is composed of Precambrian Bucaramanga Gneiss and pre-Devonian Silgara Formation intruded by Mesozoic quartz diorite, quartz monzonite, and alaskite and Cretaceous or younger porphyry. Triassic (Bocas Formation), Jurassic (Jordan and Giron Formations).and Cretaceous (Tambor, Rosa Blanca, Paja, Tablazo, Simiti, La Luna, and Umir Formations) sedimentary rocks...
Reconnaissance of sediment transport and channel morphology in the Lower Rio Bermejo Basin, Argentina - with a section on reconnaissance of the lower Rio Pilcomayo Basin, Argentina and Paraguay
John R. Ritter
1976, Open-File Report 76-564
Sediment transport conditions are described for the Lower Rio Bermejo and the Rio Pilcomayo in the Gran Chaco region of northern Argentina and southern Paraguay. The Lower Rio Bermejo is in many ways atypical, as its channel narrows downstream. Also its flow decreases downstream even though average annual rainfall at...
Availability of ground water in the area surrounding the Trident submarine construction facility, Kitsap County, Washington

1976, Open-File Report 76-351
General information is presented on water resources--with emphasis on ground-water occurrence and availability--in that part of Kitsap County (referred to as Trident Impact Area) that would be most affected by the development of the Trident submarine construction facility at Bangor, Washington. The estimated 1970 water use in the study area...
Reconnaissance of ground-water resources of the Squaxin Island Indian Reservation, Washington
W. E. Lum II, Kenneth Lyle Walters
1976, Open-File Report 76-382
A supply of fresh ground water for the Squaxin Island Indian Reservation exists in saturated deposits underlying the 3.09-square-mile island, whereas surface-water supplies are practically nonexistent. Four test wells tapped a water-hearing zone of sand and gravel and had yields ranging from 27 to 170 gallons per minute, with drawdowns...
Geochemical prospecting for Carlin-type gold deposits
Sherman P. Marsh
1976, Open-File Report 76-335
Disseminated, Carlin-type, gold deposits are associated with a volatile suite of elements consisting of Hg, As, Sb, W, and sometimes, but not always, Au. Geochemical exploration for this type of disseminated deposit depends upon recognizing the significance of this volatile suite and interpreting it in light of other geologic and...
