Boron Geochemistry of Subduction-Related Assemblages

硼的地球化学可以提供跟踪和测量弧火山海洋沉积物循环的能力。该项目将通过野外、岩石学和地球化学技术调查硼的行为，硼最初集中在海洋沉积物中，在华盛顿州喀斯喀特和阿拉斯加南部发现的与俯冲有关的组合中。研究结果将有助于阐明俯冲物质的再循环与流体污染对某些岛弧岩浆中硼异常富集的作用。

The geochemistry of boron may provide the ability to follow and measure ocean sediment recycling in arc volcanoes. This project will investigate by field, petrologic and geochemical techniques, the behavior of boron, originally concentrated in marine sediments, in subduction-related assemblages found in the Cascades, Washington and in southern Alaska. Results will help elucidate the role of recycling of subducted material versus fluid contamination as the cause of anomalous enrichment of boron in some island arc magmas.
