Geology of the Seaside-Young's River Falls area, Clatsop County, Oregon

Creator:: Tolson, Patrick Marion
Abstract:: Eight Tertiary geologic units crop out in the Seaside-Young's River Falls area, including late Oligocene to early Miocene Oswald West mudstones; Angora Peak sandstone and Silver Point members of the middle Miocene Astoria Formation, and middle Miocene Depoe Bay and Cape Foulweather Basalts. Three new lithologically distinct units, the 'J'...

Geology of the Buster Creek-Nehalem Valley area, Clatsop County, northwest Oregon

Creator:: Olbinski, James Steven
Abstract:: Six Tertiary rock units are exposed in the Buster Creek-Nehalem Valley area. They are, from oldest to youngest: upper Eocene Tillamook Volcanics; upper Eocene Cowlitz Formation; upper Eocene Keasey Formation; upper Eocene Vesper Church formation (informal); upper Eocene to Oligocene Pittsburg Bluff Formation; and middle Miocene Depoe Bay Basalt. The...

Stratigraphy and sedimentation of the Onion Peak area, Clatsop County, Oregon

Creator:: Smith, Thomas N.
Abstract:: Six Tertiary units are exposed in the Onion Peak area near the town of Cannon Beach., Oregon. The units consist of: late Eocene to early Miocene Oswald West mudstones (informal), middle Miocene Astoria Formation (Angora Peak sandstone and Silver Point mudstone members.-informal), middle Miocene basalts of intrusive and extrusive Depoe...

Stratigraphy, structure, and natural gas potential of tertiary sedimentary and volcanic units, Clatskanie 7.5 minute quadrangle, Northwest Oregon

Creator:: Eriksson, Andrew
Abstract:: The geology and natural gas potential of the Clatskanie 7.5-minute quadrangle in Columbia County, Oregon was studied utilizing a combination of geologic mapping, measuring of stratigraphic sections, diatom and molluscan fossil identifications, with subsurface geophysical data and petrographic and geochemical analyses. The stratigraphy of the study area consists of two...

Lithofacies, stratiography, and geology of the middle eocene type cowlitz formation and associated volcanic and sedimentary units, Eastern Willapa Hills, southwest Washington

Creator:: Payne, Charles William
Abstract:: Stratigraphic measurement of the 1,238-rn thick Cowlitz Formation in the southwest Washington type section along Olequa and Stillwater creeks reveals complex facies succession of wave- to tide-dominated deltaic sequences. The underlying, 625-rn thick upper member of the McIntosh Formation (as mapped by Wells, 1981) is composed of two units: a...

Stratigraphy and sedimentation of the Neahkahnie Mountain - Angora Peak area, Tillamook and Clatsop Counties, Oregon

Creator:: Cressy, Frank Beecher
Abstract:: Four distinct lithologic units compose the Tertiary rocks of the Neahkahnie Mountain - Angora Peak area, located along the northwest Oregon coast near the town of Nehalem. The Tertiary units are the late Oligocene to early Miocene Oswald West mudstones, the middle Miocene Angora Peak sandstone member of the Astoria...

Uranium mineralization of the metamorphic aureole of the Spirit pluton, Stevens County, Washington

Creator:: Mitchell, Terry Edward
Abstract:: Several uranium anomalies, with concentrations of U₃0₈ that average below 0.003 percent and reach maximums of 0.069 percent, are associated with black, fossiliferous, pyritic parts of the Ordovician Ledbetter Slate in northern Stevens County, Washington. The most uraniferous parts of the slate occur in small (average of 5 by 30...

Sequence stratigraphy and lithofacies of the middle Eocene upper McIntosh and Cowlitz Formations, geology of the Grays River Volcanics, Castle Rock - Germany Creek area, southwest Washington

Creator:: Kleibacker, Derik W.
Abstract:: A composite 732-rn thick section in Germany Creek of middle Eocene upper McIntosh and lower Cowlitz Formations, as well as the lower Grays River Volcanics, was studied using bio-, magneto- and lithostratigraphy to construct a sequence stratigraphic framework and assess hydrocarbon exploration potential. The upper McIntosh Formation forms a complete...

Geology of the Tillamook Head--Necanicum Junction area, Clatsop County, northwest Oregon

Creator:: Neel, Robert Holmes
Abstract:: Five distinct lithologic units compose the Tertiary rocks in the Tillamook Head - Necanicum Junction area of the northern Oregon Coast Range. They are: the late Eocene to early Miocene Oswald West mudstones, the middle Miocene Angora Peak sandstone and Silver Point mudstone members of the Astoria Formation, and the...
Resource Type:: Masters Thesis

Geology of the Rock Creek-Green Mountain area, southeast Clatsop and northernmost Tillamook counties, northwest Oregon

Creator:: Safley, L. Eugene
Abstract:: The middle to upper Eocene Tillamook Volcanics form the volcanic core or basement rocks in the Rock Creek-Green Mountain area. They consist of a thick sequence of high TiO2 tholeiitic basalt, basaltic andesite, and andesite subaerial flows and breccias. Detailed mapping, petrography, major oxide plots, magnetic polarity, and radiometric age...
