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...

Magmatic processes at mid-ocean ridges : evidence from lavas and melt inclusions from the Southeast Indian Ridge, the Endeavour Segment of the Juan de Fuca Ridge, and the northern East Pacific Rise

Creator:

Sours-Page, Rachel E.

Abstract:

Magmatic processes control the chemical compositions of all lavas erupted at mid-ocean ridges. In this thesis, I present studies of magmatic processes on three different mid-ocean ridges to determine which processes are in action and to what extent each has affected the chemistry of mid-ocean ridge basalts at each location....

Snow Peak, OR: late Miocene to early Pliocene volcanism in the central Cascadia forearc

Creator:

Hatfield, Ashley K.

Abstract:

Snow Peak is a voluminous shield volcano located ~50 km west of the axis of the modern Cascade arc. A previously published K-Ar age estimate indicates that the Snow Peak lavas are ~3 Ma. Subsequently, the preliminary research framework for studying the Snow Peak lavas focused on constraining the petrogenesis...

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...
