Origin & Evolution of Lavas from Lanai Volcano, Hawaii: Implications for the Source of Hawaiian Shield-Building Lavas

PI建议：（1）确定Pb，Sr和Nd同位素， 地球化学性质良好的样品， 侦察研究，（2）在拉奈岛收集更多样本 从较厚的熔岩部分，并收集玻璃从堤防，（3） 分析这些额外的样品的主要和微量元素， 和选择的样品的同位素组成，和（4）分析 从勘测研究中选择的样本， 矿物化学的额外野外工作。 样本从 厚的地层剖面将允许检查 拉奈岛时间、地球化学和同位素演化

The PIs propose to: (1) determine Pb, Sr, and Nd isotopes on the geochemically well-characterized samples from their reconnaissance study, (2) collect additional samples on Lanai from thicker sections of lava, and collect glass from dikes, (3) analyze these additional samples for major and trace elements, and selected samples for isotopic compositions, and (4) analyze selected samples from the reconnaissance study and from additional field work for mineral chemistry. Samples from a thick stratigraphic section will allow examination of the temporal, geochemical and isotopic evolution of Lanai.
