Abstract

The SUNEDCO 58-28 geothermal exploration drill hole was completed in 1981 to a depth of 2, 457 m near Breitenbush Hot Springs in the Western Cascade Mountains of northern Oregon. One hundred thirteen liquid-rich fluid inclusions (mostly secondary) were analyzed from drill cuttings samples of hydrothermal quartz, calcite, and anhydrite, as well as primary quartz phenocrysts. Except for one hydrothermal quartz specimen, minimum homogenization temperature (Th) measurements of fluid inclusions plot very close to the present measured temperatures for the drill hole. Fluid-inclusion data from near the bottom of the drill hole suggest that these rocks were altered by water of significantly greater salinity than Breitenbush Hot Springs water.
