A Synthesis of Geochemical Results from the Southeast Indian Ridge

在过去的十年中，在四个独立的实地项目中，PI从东南印度山脊（SEIR）收集了各种各样的玄武岩样本，范围在-80′e和-135′e之间。总的来说，有2000个样品，包括来自150个地方的300个玻璃组。PI建议整合和综合这些结果，并解释已解释的观测结果，其中包括与2公里以上区域深度变化有关的化学变化。这是一个非常有趣的区域，从深度、脊形态和地幔域的变化来看。除了合成外，PI还要求支持使用ELA-ICPMS（准分子激光烧蚀电感耦合等离子体质谱）对矿物及其熔体包裹体中的微量元素进行分析。

Over the last decade and during four separate field programs, the PI has collected a wide variety of basalt samples from the Southeast Indian Ridge (SEIR) between -80'E and -135'E. Overall, there are -2000 samples comprising -300 glass groups from 150 localities. The PI proposes to consolidate and synthesize these results and to interpret the explained observations, which include chemical variations related to regional depth variations of over 2 km. This is a very interesting area in terms of the observed variations in depth, ridge morphology and mantle domains. In addition to the synthesis, the PI requests some support to carry out analyses of trace elements in minerals and their melt inclusions using ELA-ICPMS (Excimer laser ablation inductively coupled plasma mass spectrometry).
