Evolution of the Corvallis fault and implications for the Oregon coast range

Creator:

Goldfinger, Chris

Abstract:

The Corvallis fault is a 50 km long northeast-trending structure, part of which defines the boundary between the central Willamette Valley and the east-central Coast Range of Oregon. Previously the fault had been mapped as either a high-angle reverse or normal fault, with the east block down. New gravity data...

Masters Thesis
Structure and tectonics of the southern Willamette Valley, Oregon

Creator:

Graven, Erik P.

Abstract:

Surface geology, seismic data, petroleum exploratory well data, and water well data have been used to analyze the structural and tectonic history of the southern Willamette Valley. Tertiary strata beneath the southern Willamette Valley appear to have had an early Cascade or Clarno volcanic source to the east by the...

Geology, structure, and tectonic history of the Tualatin Basin, northwestern Oregon

Creator:

Popowski, Thomas Allan

Abstract:

The northwest-trending Neogene Tualatin basin in northwestern Oregon is a pull-apart basin with approximately 750 m of post-middle Miocene structural relief. Gently tilted uplands capped by Columbia River Basalt Group surround the synclinal basin on all sides. Integrated gravity, aeromagnetic, and seismic reflection data indicated that the basin is underlain...

Surface-subsurface facies and distribution of the Eocene Cowlitz and Hamlet formations, northwest Oregon

Creator:

Robertson, Christina Lynn

Abstract:

Since 1979, over $114 million of natural gas has been produced at the Mist Gas Field, currently the only commercial gas field in the Pacific Northwest. In the Mist Gas Field, the sandstone-dominated Clark and Wilson member of the upper Eocene Cowlitz Formation is the reservoir and the overlying upper...

Surface-subsurface geology of the middle to upper Eocene sedimentary and volcanic rock units, western Columbia County, northwest Oregon

Creator:

Berkman, Thomas Anthony

Abstract:

The middle to upper Eocene Tillamook Volcanics form the basement in the Rock Creek - Rocky Point area. These tholeiitic to alkalic basalts, basaltic andesites, and andesites were erupted as shield volcanoes seaward of the strandline ontop of an older deep-marine mudstone unit (Yamhill Formation) and an accreted portion of...

Masters Thesis
Geology and geochemistry of Juniper Ridge, Horsehead Mountain and Burns Butte : implications for the petrogenesis of silicic magma on the High Lava Plains, southeastern Oregon

Creator:

MacLean, James W.

Abstract:

The Juniper Ridge volcanic complex is located in the High Lava Plains Province of southeastern Oregon, a wide zone of bimodal volcanism and faulting that marks the northern limit of widespread Basin and Range-style faulting in the northern Great Basin Province. Rhyolite dome complexes are progressively younger to the northwest...

Geology and petrologic evolution of the silicic to intermediate volcanic rocks underneath Steens Mountain basalt, SE Oregon

Creator:

Langer, Vera W.

Abstract:

Steens Mountain in SE Oregon is part of the northern Basin and Range Province, and represents a horst tilted about 100 to the west that is bounded to the east by a high angle, NNE trending normal fault. The minimum displacement is about 1200 m. Volcanic rocks, exposed along the...
