Investigation on the generation of primitive basalts in the southern Washington Cascades
An investigation of the petrography, mineralogy and chemistry of primitive basalts found in a E-W transect of southern Washington and northern Oregon provides constraints concerning the thermal structure and composition ...
Trace element geochemistry of basalts from the Oregon Cascade Range: Implications for magma generation and possible variations in the sub-arc mantle
Analyses of Oregon Cascades basalts reveal two groups of High Cascades (9-0 Ma) lavas: (1) "enriched" basalts with high Ba, Sr, Ba/Nb, and Ba/La, and (2) "depleted" basalts with flat rare earth element patterns and relatively ...
