中文摘要
夏威夷群岛链是地球上最活跃的地幔热柱之一(“热点”)的表面表现。通过测量夏威夷岛链上年轻玄武岩的U系列不平衡、主量元素和微量元素组成以及Nd值和Sr值,将确定夏威夷岩柱的熔融条件。为此,我们将分析一套岩石,其中包括来自火山的熔岩,这些熔岩从夏威夷链的前缘延伸到后端,覆盖了夏威夷熔岩展示的大部分地球化学范围。该项目的主要目标将是利用岛链上的这一“零年龄”时间片、U系列测量结果和熔融数值模型来描述从羽流核心到边缘的熔融动力学变化。
英文摘要
SimsEAR-9909473The chain of Hawaiian Islands is the surface expression of one of the most active mantle plumes ('hot spots') on Earth. Measurements of U-series disequilibria, major and trace element compositions and Nd, and Sr isotopic ratios in young basalts from across the Hawaiian Island chain will be used to determine melting conditions in the Hawaiian plume. For that purpose, we will analyze a suite of rocks that include lavas from volcanoes that extend from the leading edge to the trailing end of the Hawaiian chain and cover most of the geochemical range exhibited by Hawaiian lavas. The main objective of this project will be to use this "zero age" time slice along the island chain, the U-series measurements, and numerical models of melting to characterize the change in melting dynamics from the core of the plume to its fringes.
