REU: Geochemical Evolution of Hawaiian Lavas: Temporal Variation of Loihi Seamount and Evaluation of Gloria Survey Results on Hawaii

这是一项被认为是对之前夏威夷火山地球化学研究工作的延续。它有三个主要组成部分：(1)分析Alvin获得的Loihi熔岩样品，(2)通过使用双鱼V型潜水器潜水获得额外的Loihi样品，(3)挖掘和分析(A)Gloria勘测似乎是来自Kilauea和Loihi的大型“洪水玄武岩”的样品，(B)夏威夷拱顶上的玄武岩，可能是火山的初始阶段；和(C)来自Mahukona海山的样品。这项提议得到的支持程度有所降低。重点将是分析来自Loihi和Mahukona的现有样品，以及双鱼座V.Loihi获得的新样品，这是夏威夷最年轻的火山，这项研究获得的结果将对理解热点火山活动及其时间演化具有重要意义。

This is a proposal that is considered as a continuation of previous work on the geochemistry of Hawaiian volcanoes. There are three principal components: (1) analyze samples of Loihi lavas obtained by ALVIN, (2) obtain additional samples of Loihi by diving with Pisces V submersible, (3) dredge and analyze (a) samples of what appear on GLORIA surveys to be large "flood basalts" from Kilauea and Loihi, (b) basalts on the Hawaiian arch that may be the very initial phases of a volcano, and (c) samples from Mahukona seamount. This proposal is being supported at a reduced level. The emphasis will be on analyzing existing samples from Loihi and Mahukona and new samples obtained by Pisces V. Loihi is the youngest Hawaiian volcano and the results obtained from this study will be important for understanding 'hot spot' volcanism and its temporal evolution.
