Collaborative Research: Mauna Loa Submarine Picritic Basalts: Implications for Primary Magmas from the Hawaiian Plume

小行星9503222 提出了一个为期三年的计划，以收集和研究岩石从西南裂谷带的莫纳罗亚火山，夏威夷。 这一地区的许多岩石是苦橄岩，深部喷发可能是由于导管系统深处的致密岩浆汇集而导致岩浆密度过滤的结果。 另一种选择是，在拟议的滑塌表面上暴露的熔岩比陆上熔岩更古老，因此显示出熔岩化学的时间变化。 这些熔岩特别有趣，因为它们是在夏威夷或其他类似岛屿上发现的镁含量最高的熔岩，这些玻璃可以告诉我们很多关于地幔如何熔化以及熔化物如何被输送到表面的信息。 ***

9503222 Garcia A three-year plan is proposed for the collection and study of rocks from the southwest rift zone of Mauna Loa volcano, Hawaii. Many rocks from this area are picrites and it is possible that the deep eruptions are a result of density filtering of the magmas due to pooling of dense magmas deep within the conduit system. The alternative is that the lavas exposed on the proposed slump surface are older than subaerial lavas and therefore show a temporal variation of chemistry of lavas. These lavas are particularly interesting because they are the most Mg-rich lavas ever found on Hawaii or other similar island and these glasses can tell us much about how the mantle melts and how the melts are transported to the surface. ***
