Geochemical and Dynamical Evolution of the Galapagos Hotspot (Renewal)

该项目是为了继续研究海底熔岩样本， 1990年从加拉帕戈斯平台收集的地球物理数据。 地球化学研究证实并延伸了一个马蹄形图案 地球化学分带在陆上和 加拉帕戈斯热点的海底喷发产物。 的 主要调查人员目前正在收集主要和微量 元素浓度、同位素比值和放射性年龄数据 从一个广泛的海底火山岩和玻璃套， 为了验证这些假设。

This project is for continued study of submarine lava samples and geophysical data collected from the Galapagos platform in 1990. Geochemical studies confirm and extend a horseshoe-shaped pattern of geochemical zonation in the zonation in the subaerial and submarine eruptive products of the Galapagos hotspot. The principal investigators are presently collecting major and trace element concentrations, isotopic ratios, and radiomatic age data from an extensive suite of submarine volcanic rocks and glasses in order to test these hypotheses.
