Potential Petroleum Reservoir Rocks of North-Central Oregon
… to determine if potential petroleum reservoir rocks do exist in north-central Oregon. Through field and laboratory study and by comparing this region with petroleum producing basins with volcanic and volcaniclastic reservoirs, I have determined that the potential volcanic and volcaniclastic …

Helium isotope geochemistry of oceanic volcanic rocks : implications for mantle heterogeneity and degassing
The concentrations and isotopic compositions of helium have been measured in a number of mantle derived oceanic basalts. The goal of this research is to use the helium isotopic systematics to constrain the nature and origin of mantle heterogeneity in the oceanic mantle. Studies of helium …

Conduction Plus Convection Heat Flow Modeling for the Linga Complex, Peruvian Coastal Batholith
<p>Factors affecting the thermal evolution of the Linga magmatic intrusion in the Ica-Pisco area of the Peruvian Coastal Batholith were studied using field work, petrography, geochemistry data, and computer modeling. Field work and petrography involved collecting samples for geochemical analysis …

Electrical and seismic responses of shallow, volcanogenic, massive sulphide ore deposits
… not easily distinguished from polarizable host rocks. Second order responses, at Woodlawn, better define these lithologies and cross-plots of EM coupling removed first order parameters prove useful. The supergene and gossan zones are defined as sources of electrical anomalies and correlate with …
