9521344 Orcutt These investigators have collected seismic data within the Australian-Antarctic Discordance to measure the crustal thickness for two neighboring segments. These data will provide a crucial test of the relationship between axial basalt chemistry, crustal thickness, and axial depth since the Discordance is an end-member in terms of depth for a given spreading rate. This grant will allow the investigators to finalize the analyses of these data. ***

小行星9521344 这些研究人员收集了澳大利亚-南极不一致区域内的地震数据，以测量两个相邻部分的地壳厚度。 这些数据将提供一个重要的测试轴向玄武岩化学，地壳厚度和轴向深度之间的关系，因为不一致性是一个端元的深度为一个给定的扩展速率。 这笔赠款将使研究人员能够完成对这些数据的分析。 ***
