The goal of this research project is to gain a clearer understanding of the magmatic processes in the upper mantle and oceanic crust at mid-ocean ridge (MOR) spreading centers. The purpose of this project is to investigate the possible mechanisms that would produce these basalts with unusually high plagioclase contents at fast spreading centers.The conclusions of this investigation will provide insights into the chemical and physical mechanisms that occur to produce the plagioclase ultra-phyric basalts found in MORB environments. This project will provide crucial understanding to a previously unexplored inquiry regarding the origin of PUBs at intermediate to fast-spreading centers and transform faults.
