The Stratigraphy And Structure Of The Columbia River Basalt In The Clackamas River Drainage, James Lee Anderson Jan 1978

The Stratigraphy And Structure Of The Columbia River Basalt In The Clackamas River Drainage, James Lee Anderson

Dissertations and Theses

The Clackamas River drainage within the western Cascade Range is approximately aligned with a northwest trending lineation defined by the Portland Hills and the Brothers Fault zone. This area is occupied by an extensive Columbia River Basalt sequence that is deeply incised by the Clackamas River and its tributaries. Two major basalt units of the Yakima Basalt Subgroup, including the Grande Ronde Basalt and the Frenchman Springs Member of the Wanapurn Basalt, are distinguishable in a 515 meter to 550 meter accumulation. Of particular interest is the presence of five trending right-lateral strike-slip faults is consistent with a stress model …

Geometry And Depositional Systems Of The Orr And Patterson Sands, Bloyd Formation (Pennsylvanian), Eastern Franklin And Western Johnson Counties, Arkansas, Michael E. Corbin Jan 1978

Geometry And Depositional Systems Of The Orr And Patterson Sands, Bloyd Formation (Pennsylvanian), Eastern Franklin And Western Johnson Counties, Arkansas, Michael E. Corbin

Journal of the Arkansas Academy of Science

The Orr and Patterson sandstones occur in the Trace Creek Shale Member, Bloyd Formation, in surface exposures on the northern Arkansas structural platform. The Orr sandstone exhibits regional thickening trends to the south and southeast into the Arkoma Basin as shown by isolith maps for the area studied. The depositional environment that formed this sandstone comprised fluvial or deltaic channels feeding a destructive delta system to the southeast. The Patterson sandstone lies stratigraphically above the Orr sandstone, and is confined essentially to Franklin and Johnson counties. It is poorly developed or not present in Washington and western Crawford Counties. The …

Depositional Systems Of The Sells And Cecil Sandstones, Atoka Formation (Pennsylvanian), Eastern Crawford And Western Franklin Counties, Arkansas, Chris A. Cardneaux Jan 1978

Depositional Systems Of The Sells And Cecil Sandstones, Atoka Formation (Pennsylvanian), Eastern Crawford And Western Franklin Counties, Arkansas, Chris A. Cardneaux

Journal of the Arkansas Academy of Science

The Cecil and Sells sandstones of the Atoka Formation (Pennsylvanian) were studied in the subsurface of eastern Crawford and western Franklin Counties. Sand of the Cecil sandstone was delivered to a high destructive, wave dominated delta southeast of Fort Smith and reworked laterally by longshore currents to form coastal barrier sands to the east. The Sells sandstone unit accumulated as a distributary channel system that bifurcates to the southeast and southwest. The interdistributary areas are characterized by immature sands interbedded with shales. These immature sands were deposited by crevasse splays and reworking of the distributary mouth bars by marine processes …

Stratigraphy, Depositional Environment And Structure Of The Taconic Allochthon, Central Washington County, New York, Louise D. Jacobi Jan 1977

Stratigraphy, Depositional Environment And Structure Of The Taconic Allochthon, Central Washington County, New York, Louise D. Jacobi

Geology Theses and Dissertations

The Taconic Allochthon contains rocks of Cambrian (?), Cambrian and Ordovician age. It measures approximately 200 kilometers by 25 kilometers and is located in contiguous sections of New York, Vermont, Massachusetts, and Connecticut. The rocks are predominantly slates with lesser amounts of arenites, wackes, limestone, chert, and conglomerates. All have been subjected to chlorite or biotite grade metamorphism and two tectonic deformations. The study area in central Washington County, New York, contains most of the Taconic sequence, and because of both natural and man-made exposure it is more accessible than most other locations. A lithostratigraphic column has been identified which …
