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.

这是一项被认为是 夏威夷火山的地球化学研究。 那里 有三个主成分：（1）分析样本Loihi ALVIN获得的熔岩，（2）获得Loihi的额外样品 通过使用双鱼座V潜水器潜水，（3）疏浚和分析（a） 格洛丽亚调查中出现的大型“洪水”样本 来自基拉韦厄和洛伊希的玄武岩，（B）夏威夷拱门上的玄武岩 这可能是一个火山的初始阶段，和（c）样本 来自马胡科纳海山。该提案得到了A 降低水平。 重点是分析现有的 从Loihi和Mahukona获得的样本以及 Pisces V. Loihi是夏威夷最年轻的火山， 从这项研究中获得的信息将对理解“热”很重要。 点火山作用及其时间演化
