Subduction of an oceanic plate beneath the Bering Strait region resulted in the formation of an extensive magmatic belt along the margin of the region during the Cretaceous. Plutons and gneiss domes of this age are broadly ...
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 ...
