This POWRE award provides funding to complete a geochemical study of basaltic rocks recovered from the Central Basin Fault of the West Philippine Basin. Samples were previously collected by the PI through participation in a JAMSTEC research cruise and will be analyzed for trace element abundance and Sr, Nd and Pb isotopes. The objective of the work is to investigate the geochemical influence of subduction on the chemical composition of magma erupted at a spreading ridge. The PI will collaborate on this project with Japanese scientists. This international collaboration will allow the PI to take a leadership role in international geochemical research and will lead to expanded research opportunities for her and her students.

这项POWRE奖提供资金，以完成从菲律宾西部盆地中央盆地断层中恢复的玄武岩的地球化学研究。样品之前是由国际和平研究所通过参加JAMSTEC研究巡航收集的，将分析微量元素丰度和锶、钕和铅同位素。这项工作的目的是调查俯冲作用对在扩张山脊喷发的岩浆化学成分的影响。国际和平研究所将与日本科学家在这个项目上进行合作。这一国际合作将使PI在国际地球化学研究中发挥领导作用，并将为她和她的学生带来更多的研究机会。
