这是一个分析微量元素和同位素的建议,来自冰岛和MAR的数百个样本。一个重要的目标是创建一个大型的样本数据集,所有样本都具有每个样本的主要元素,微量元素和Sr,Nd,Pd和Hf同位素。有了这一数据集,研究所将试图回答与冰岛羽流与MAR在各种空间和时间尺度上的相互作用有关的各种具体问题/假设。这些问题涉及的问题,不同的地幔成分,其起源和演化,以及各种成分之间的歧视混合参与者在冰岛和MAR熔岩。
英文摘要
This is a proposal to analyze for trace elements and isotopes, many hundreds of samples from Iceland, and the MAR. An important goal is to create a large data set of samples that all have major elements, trace elements and Sr, Nd, Pd, and Hf isotopes determined for each sample. With this data set, the PIs will try to answer a variety of specific questions/hypotheses related to the interaction of the Iceland plume with the MAR over a variety of spatial and temporal scales. These questions concern issues related to diverse mantle components, their origin and evolution, and discrimination between various components as mixing participants in the Icelandic and MAR lavas.
