An Experimental and Analytical Investigation of the Parameters that Influence Measured CO₂ in Plagioclase-Hosted Melt Inclusions in MORBs

Creator:

Drignon, Melissa J.

Abstract:

To understand the processes that lead to the formation of the oceanic crust, one must know the composition and the depth at which primary melts originate. Towards this end, this dissertation focuses on plagioclase-hosted melt inclusions from plagioclase ultraphyric basalts (PUBs). Plagioclase is usually considered to be the second phase,...

Magmatic processes beneath mid-ocean ridges : insights from mineral and glass chemistry in plagioclase ultraphyric basalts

Creator:

Lange, Amy E.

Abstract:

Prior to eruption at mid-ocean ridges, melts must travel through >6 km of crust from their origin in the mantle. The final composition of the melts is dependent on both the melting conditions and magmatic processes within the crust. While mid-ocean ridge basalt (MORB) glasses are commonly used to infer...
