This project is a geochemical study of volcanic rocks from the West Antarctic Rift system. Its goal is to understand the link between mantle composition and the diverse, regional geodynamic processes, which include uplift, rifting, and volcanism. This project uses argon dating to time the processes, and isotope geochemistry and melt inclusion studies to determine whether the area is underlain by hot or wet mantle. The main broader impacts are support for a woman graduate student, undergraduate research, and research infrastructure.

这个项目是对西南极裂谷系统中的火山岩进行的地球化学研究。它的目标是了解地幔组成和不同的区域地球动力学过程之间的联系，包括抬升、裂谷和火山作用。该项目使用Ar测年来确定过程的时间，并使用同位素地球化学和熔融包裹体研究来确定该地区是被热的地幔还是湿的地幔所覆盖。主要的更广泛的影响是对女研究生、本科生研究和研究基础设施的支持。
