Surface-subsurface geology of the middle to upper Eocene sedimentary and volcanic rock units, western Columbia County, northwest Oregon

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...

Seismotectonics in the eastern Precordillera, San Juan, Argentina : reconciling earthquakes and structural geology in the vicinity of the 1944 earthquake for a new model of crustal-scale deformation

Creator:

Schiffman, Celia Rose

Abstract:

This thesis synthesizes surficial structural data, a detailed analysis of an earthquake in 1944, and historical seismicity into a new model of crustal scale deformation in the eastern Precordillera in northwestern Argentina in the vicinity of San Juan. The eastern Precordillera was uplifted during previous thin-skinned deformation episodes, and is...
