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从东南印度洋脊（SEIR）收集了各种各样的玄武岩样本，位于-80 'E和-135' E之间。总的来说，有约2000个样品，包括来自150个地点的约300个玻璃组。PI建议巩固和综合这些结果，并解释解释的意见，其中包括与区域深度变化超过2公里的化学变化。这是一个非常有趣的地区，在深度，山脊形态和地幔域的变化。除综合报告外，PI还要求提供一些支持，以便使用ELA-ICPMS（准分子激光烧蚀电感耦合等离子体质谱法）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).
