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.

这是一项对来自冰岛和MAR的数百个样品进行微量元素和同位素分析的建议。一个重要的目标是创建一个庞大的样本数据集，其中所有的样本都有为每个样本确定的主要元素、微量元素和锶、钕、钯和氢同位素。利用这一数据集，指数将试图回答与冰岛羽流与MAR在各种空间和时间尺度上相互作用有关的各种具体问题/假设。这些问题涉及与不同的地幔成分有关的问题，它们的起源和演化，以及作为冰岛熔岩和马拉熔岩混合参与者的不同成分之间的歧视。
