Geology and geothermal resources of Mt. Hood area, Oregon

SP-14, Special Publication: Geothermal exploration should be concentrated in the High Cascade heat-flow anomaly and the somewhat higher Mount Hood heat-flow anomaly where permeable rocks are present in thermal zones. Permeable rocks and hydrothermal circulation systems are most probably where Columbia River basalt or phaneritic plutonic rocks occur and where fracture permeability has been enhanced by faulting. North-south-trending normal faults and ?pressure shadows? in northwest-trending faults with strike-slip motion are probably the most favorable structures for fracture permeability. Intersection of these structures with the Laurel Hill and Still Creek plutons and areas near youthful volcanic vents on the north and east sides of Mount Hood are very favorable exploration targets, especially where the Columbia River Basalt Group is present at depth.
