Creator:: Nelson, Storr L.
Abstract:: Lower and Middle Devonian strata crop out on the former stable carbonate platform that existed in the Quinn Canyon Range, through the carbonate shelf edge in the Pancake Range, to the carbonate slope and outer-shelf basin in the Reveille Range. The strata of the Reveille Range record a transition from...

Creator:: Rarey, Phillip Jay
Abstract:: The middle to late Eocene tholeiitic Tillamook Volcanics compose the oldest rock unit in the Hamlet-North Fork of the Nehalem River area. Geochemical plots and field relationships indicate that these rocks were produced in an extensional tectonic setting in the developing forearc and formed an extensive tholeiltic oceanic island. The...

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...

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...

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...

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...

Creator:: Moothart, Steve Rene'
Abstract:: The early to middle Eocene submarine basalts of the Crescent Formation form the core and basement of the structurally uplifted Willapa Hills region of southwest Washington. The formation consists of a thick sequence of predominantly subalkaline, tholeiitic pillow basalts and breccias formed as oceanic crust and seamounts at a sea...
