Geochemical Modeling of Young Basalts

在过去的三年中，pi已经将来自发散和收敛板块边缘的主要元素数据综合到地幔融化的定量模型中，这些模型在构造背景下解释了全球系统。虽然这些模型需要测试，但它们为理解岩石成因的许多相关问题提供了工具。该项目将检查海洋岛屿玄武岩的全球数据库，以测试主要元素熔化模型在板块内火山活动的构造背景下的工作效果。此外，将扩展主元素模型，以研究主元素与微量元素之间的关系

During the past three years the PIs have synthesized major element data from divergent and convergent plate margins into quantitative models of mantle melting that account for the global systematics in a tectonic context. While these models need to be tested, they provide a tool for understanding many related problems of petrogenesis. This project will examine the global data base for ocean island basalts to test how well the major element melting models work in the tectonic setting of within-plate volcanism. In addition, the major element models will be extended to investigate the relationship between the major and trace elements
