中文摘要
这是一次地壳增生的综合地球化学和地球化学调查,比较了沿西南印度海脊从10E到23E长900公里的两个几何形状截然不同的超分段。这项研究的目的是确定先前未绘制的高度倾斜的海脊超分段的分段和重力结构,并获得两个超分段的代表性样本,以确定它们的地质、海脊结构和地球化学,以及它们对截然不同的地幔上涌速率和扩张几何的响应。
英文摘要
This is an integrated geochemical and geochemical investigation of crustal accretion, comparing two supersegments with strikingly different geometry along a 900-km section of the SW Indian Ridge from 10E to 23E. The objectives of the study are to determine the segmentation and gravity structure of the previously unmapped highly oblique ridge supersegment, and to obtain a representative sampling of the two supersegments to ascertain their geology, ridge architecture, and geochemistry, and how these have responded to dramatically diferent mantle upwelling rates and spreading geometry.
