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...

Geology of the Elsie-lower Nehalem River area, south-central Clatsop and northern Tillamook counties, northwestern Oregon

Creator:: Mumford, Daniel Franklin
Abstract:: The middle Eocene Tillamook Volcanics form the oldest rock unit in the Elsie-lower Nehalem River area. K-Ar age determinations and age constraints imposed by foraminiferal and calcareous nannofossil assemblages of overlying sedimentary strata indicate an absolute age of about 42 Ma for the uppermost Tillamook Volcanics. Major oxide values indicate...

Geology of the Hamlet-North Fork of the Nehalem River area, southern Clatsop and northernmost Tillamook Counties, northwest Oregon

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...

Multivariate analysis of a tidal marsh ecosystem at Netarts Spit, Tillamook County, Oregon

Creator:: Liverman, Marc C.
Abstract:: Variability of plant species distributions, plant connunities, soil and hydrological factors in an area of the Netarts Spit tidal marsh are examined. The purpose is to advance general understanding of Oregon's tidal marsh ecosystems in terms of plant coninunities and functio'nal habitat conditions and make a contribution to the conceptual...
