Accomplishment Based Renewal: Volatiles in Submarine Magmas: An Experimental and Analytical Study

小行星9416747 这是一项基于成就的更新请求，以继续研究玄武岩中的挥发物。 这一点很重要，因为地幔中少量的水和二氧化碳对熔融量和岩浆的成分有很大的影响。 这项研究将集中在水和二氧化碳的数量，氘氢比，以及弧后盆地玄武岩中微量元素的丰度。 他们将确定玄武岩的同位素组成，以了解俯冲板块上方地幔的可变组成对熔岩组成的影响。 他们还将进行实验，以了解水对地幔岩石融化的影响。 ***

9416747 Stolper This is a request for an Accomplishment Based Renewal (ABR) to continue the study of volatiles in basalts. This is important because small amounts of water and carbon dioxide in the mantle have a large effect on the amount of melting and the composition of magmas. The research will focus on the amount of water and carbon dioxide, the ratio of deuterium to hydrogen, and the abundance of trace elements in back-arc basin basalts. They will determine the isotopic composition of basalts to understand the effect of the variable composition of the mantle above a subducting plate on the compositions of lavas. They will also conduct experiments to understand the effect of water on the melting of mantle rocks. ***
