Constraints of the origin of the middle Pleistocene transition from the glacial sedimentary record of the north-central United States

Creator:

Roy, Martin

Abstract:

This dissertation focuses on the role of ice sheets in the transition during the middle Pleistocene (-1.2 Ma) from 41-kyr glacial cycles to 100-kyr glacial cycles. This research evaluates the hypothesis that the middle Pleistocene transition (MPT) was related to the glacial erosion of a regolith mantle and the subsequent...

Dissertation
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...

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...
