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.

Dasgupta/Classa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。资金用于进行高压实验，以调查沉积物逐渐俯冲到更深处时的命运。特别是，与俯冲工厂倡议的主要目标相关的两个主要问题被解决：(1)二氧化碳(以碳酸盐的形式)对俯冲沉积物的熔融行为有什么影响，以及(2)碳酸盐沉积物熔融对俯冲工厂内主要、痕量和挥发性元素的质量传递和质量平衡有什么作用？更广泛的影响包括一名新的年轻研究员和一名女性软货币研究员(LDEO)的支持。它还将支持赖斯大学的一名研究生。并让本科生参与到研究中来。
