Magmatic sulfides from Yerington, Nevada, and Yanacocha, Peru, were analyzed by laser ablation-inductively coupled mass spectrometry (LA-ICPMS) and electron microprobe to determine copper, gold, and silver concentrations and ratios in order to examine the relationship to the metal content of related magmatic-hydrothermal ores. The magmatic sulfides occur in plutonic rocks...

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...

There are approximately 4,000,000 acres of cut-over and burned-over land in western Washington and Oregon which are either non-stocked or unsatisfactorily stocked with young forest growth. This brings about a great need for a quick and efficient method of land examination from which to plan reforestation measures and make up...

Oregon is the number one producer of cool-season grass seed in the United
States. The center of the grass seed industry of Oregon is located in the Willamette
Valley, where about 470,000 acres of seed are grown. Innovative grass seed growers
of the area are beginning to implement precision agriculture...
