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.

这是分析微量元素和同位素，来自冰岛和3月的数百个样本的建议。一个重要的目标是创建一个大型数据集，这些样本都具有主要元素，跟踪元素和SR，ND，PD和HF同位素，为每个样品确定。使用此数据集，PI将尝试回答与冰岛羽流与MAR相互作用相关的各种特定问题/假设，这是在各种空间和时间尺度上。这些问题涉及与各种地幔组成部分，其起源和进化以及各种组成部分之间的歧视有关的问题，以混合冰岛和MAR熔岩中的参与者。
