The Petrogenesis of Near-Primary MORB Melt Inclusions: Implications Regarding Mantle Melting and Differentiation Processes

在这个项目中，P.I.s将分析原始成分（Fo90橄榄石，An90斜长石）的主要元素和微量元素化学。这种成分的熔岩在morb中很少见，但在离轴区域发现过。私家侦探认为，这些熔体可能是重要的初级morb。他们将重新均匀化包裹体，以探索包裹后变化的影响。最后，他们将对这些熔体进行1-atm实验。他们的最终目标是确定在morb可能产生这种熔体的条件。

In this project, the P.I.s will analyze major and trace element chemistry of primitive compositions (Fo90 olivine,An90 plagioclase). Lavas of such compositions are rare in MORBs but have been found in off-axis areas. The P.I.s argue that these melts could be important primary MORBs. They will rehomogenize the inclusions to explore the effects of post-entrapment changes. Finally, they will run 1-atm experiment on these melts. Their ultimate objective is to determine the conditions under which such melts may be generated at MORBs.
