MARGINS: Collaborative Research: Melting of Carbonate-bearing Sediments in Subduction Zones

Dasgupta/Class该奖项是根据2009年美国复苏和再投资法案（公法111-2）资助的。该基金用于进行高压实验，以调查沉积物的命运，因为它们逐渐俯冲到更大的深度。 特别是，两个主要的问题是相关的俯冲工厂倡议的MARGINS的主要目标：（1）什么是二氧化碳（以碳酸盐的形式）对俯冲沉积物的熔融行为的影响，和（2）碳酸盐沉积物熔融的作用是什么？质量转移和质量平衡的主要，微量和挥发性元素在整个俯冲工厂？更广泛的影响包括支持一名新的年轻调查员和一名女性软钱研究员。它还将支持赖斯的一名研究生。并让本科生参与到研究的各个方面。

Dasgupta/ClassThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-2).Fund are provided for conducting high-pressure experiments to investigate the fate of sediments as they are progressively subducted to greater depths. In particular, two major questions are addressed that are relevant to the chief goals of the Subduction Factory initiative of MARGINS: (1) What is the effect of CO2 (in the form of carbonates) on the melting behavior of subducting sediments, and (2) What is the role of carbonated sediment melting on mass transfer and mass balance of major, trace, and volatile elements across the subduction factory?Broader impacts include support of a new young investigator and a female soft-money researcher (LDEO). It would also support a graduate student at Rice. And also involve undergraduate students in aspects of the research.
