There is a lack of consensus regarding the roles of sulfide saturation versus volatile degassing on the partitioning of Cu and Ag during differentiation and eruption of convergent margin magmas. Because of their oxidized character, volatile-rich magmas from the Eastern Manus Back-arc Basin (EMBB) only reach sulfide saturation following magnetite-driven...

In 2008, the Department of Land Conservation and Development (DLCD) asked the Institute for Natural Resources (INR) to assess whether the Oregon Land Use Program, as designed, is helping the state meet its land use goals. More specifically, this intensive but highly time-limited research effort set out to answer the...
The Horsetail Creek Bridge (HCB), constructed in 1914, is located along the Historic Columbia River Highway in Oregon. The original cross beams from the HCB were substantially deficient in shear strength, particularly for the projected increase in traffic loads. One control beam and three beams with varying configurations of a...

The primary goal of this study is to assess the impact of a subduction component
added to the mantle wedge beneath the Oregon Cascades to the composition and fO2 of
primitive Cascade basalts. Olivine-hosted melt inclusions from compositionally diverse
basalts across the Cascade arc (~100 km) are utilized in an...

Satellite image interpretation, geologic mapping, and paleoseismic trenching are
used to investigate the Trans-Yamuna active fault system in the northwestern Doon Valley
of the Indian Himalayan foothills. This east-west fault system is subparallel to and crosses
the Main Boundary thrust near the structural transition from the Nahan salient to the...

This issue of the PMFC bulletin focuses primarily on the English sole, including results of tagging off of various coasts and studies of various populations of English sole. It also gives a review of sablefish tagging in California and details the Oregon trawl fishery for mink food up to 1965.
