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

这一建议被认为是对夏威夷火山地球化学先前工作的延续。有三个主要组成部分：(1)分析ALVIN获得的Loihi熔岩样本，(2)通过双鱼座V潜水器潜水获得Loihi的额外样本，(3)挖掘和分析(a) GLORIA调查显示来自基拉韦厄和Loihi的大型“洪水玄武岩”样本，(b)夏威夷拱上可能是火山最初阶段的玄武岩样本，以及(c)来自Mahukona海山的样本。这项建议得到了较低水平的支持。重点将放在分析来自Loihi和Mahukona的现有样本以及双鱼座V.获得的新样本上。Loihi是夏威夷最年轻的火山，从这项研究中获得的结果对于理解“热点”火山作用及其时间演化非常重要。

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.
