Integrated Geophysical Exploration Of A Known Geothermal Resource: Neal Hot Springs, Clinton Ryan Colwell
Integrated Geophysical Exploration Of A Known Geothermal Resource: Neal Hot Springs, Clinton Ryan Colwell
Boise State University Theses and Dissertations
I present an integrated geophysical characterization of the Neal Hot Springs geothermal system in eastern Oregon. This newly established 23 MW geothermal production site is located in a region of complex geology and intersecting faults associated with two major extensional systems; the Oregon-Idaho Graben and the western Snake River Plain. The intersection of two dominant fault orientations, coupled with a high geothermal gradient from relatively thin continental crust and radioactive decay from a shallow granitic body, produces the pathways and heat needed for deep water circulation at Neal Hot Springs. New geologic mapping, geochemistry, and measurements from several boreholes in …

Age, Provenance, And Structure Of The Weatherby Formation, Eastern Izee Sub-Basin, Blue Mountains Province, Oregon And Idaho, Bryant Douglas Ware
Boise State University Theses and Dissertations
The terranes of the Blue Mountains province of eastern Oregon and west-central Idaho provide an important link between the geology of the North American Cordillera exposed in Canada and Alaska in the north and Nevada and California in the south. The Izee basin is a volcanic-rich sedimentary sequence onlapping the volcanic arc and accretionary mélange terranes of the Blue Mountains, and comprises the marine flysch Weatherby Formation at its eastern extent. This study sought to establish the stratigraphic and structural relationships between the Weatherby Formation and the proximal Baker and Olds Ferry terranes. Small-scale mapping, structural measurements, and geochronological data …
