Research on the Physical Properties of Geothermal Reservoir Rocks. Summary Report on Collection of Samples of Volcanic Rocks for Petrophysical Studies. Progress Report 1

摘要

Rock samples were collected from the Snake River Plain volcanic depression of Idaho, the Columbia Plateau's volcanic basin located in southeastern Washington, northeastern Oregon, and western Idaho, the Modoc volcanic province of northeastern California, the volcanic fields of south central Nevada, and the Jemez volcanic field of north central New Mexico. Strategy governing sample selection is described. From each field, 64 individual rock samples, each being several kilograms in size, were collected. (ERA citation 02:045307)
