Geochemical Studies of Ocean Basin Evolution

该项目的目标是进行同位素和 微量元素研究：（1）大西洋中脊著名地区， (2)戈尔达山脊、埃斯卡纳巴海槽和杰克逊总统 海隆;（3）沃尔维斯海岭、格兰德河海隆和喀麦隆 行海山。主要重点是著名的地区，试图 将同位素和微量元素数据证据与 岩浆房与岩石学证据之一， 将微量元素和同位素数据与同伴进行比较 对东太平洋海隆的岩石进行研究。 %%% 我们对岩浆多样性的认识大多来自于 了解熔体来源的源岩，以及 岩浆分异的过程。 这些信息来自 这主要来自于对微量元素变化的理解， 暴露在海底的熔岩的同位素组成。 博士 白色在获得这类数据方面有着出色的记录， 从海底采集的岩石 预计这一 该项目将提供有关海底岩浆的重要信息 流程.

The objective of this project is to carry out isotopic and trace element studies of (1) FAMOUS area of Mid-Atlantic Ridge, (2) Gorda Ridge, Escanaba Trough, and President Jackson Seamounts, and (3) Walvis Ridge, Rio Grande Rise and Cameroon Line Seamounts. Principal focus is on FAMOUS area to try to reconcile isotopic and trace element data evidence against a magma chamber with the petrological evidence for one, and to compare trace element and isotopic data with that from companion study being carried out on rocks from the East Pacific Rise. %%% Much of our knowledge of magmatic diversity come from a knowledge of the source rocks from which melts are derived, and the processes of magmatic fractionation. This information comes largely from an understanding of variations in trace element and isotopic composition of lavas exposed on the sea floor. Dr. White has an excellent record for obtaining this type of data on rocks collected from the sea floor. It is expected that this project will yield important information on sea floor magmatic processes.
