Masters Thesis
Olivine and plagioclase-hosted melt inclusions and their application to determining parental arc magmas

Creator:

Kohut, Edward John

Abstract:

Three broadly interrelated problems of critical significance to the proper interpretation of melt inclusion (MI) data are addressed in this thesis. The first issue, the petrogenesis of anorthitic plagioclase phenocrysts in MORB lavas, has relevance due to the presence of numerous MI in many high-An feldspars. This problem was addressed...

Dissertation
The role of subduction fluids in generating compositionally diverse basalts in the Cascadia subduction zone

Creator:

Rowe, Michael C.

Abstract:

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...
