An Isotopic Study of Lavas from the Louisville Seamount Chain

研究人员将对25个样品进行Nd、Pb和Sr分析，这些岩石是在一个已经资助的NSF-ODP项目中疏浚的，该项目旨在调查路易斯维尔海山链（LSC）。通过将结果与已经资助的项目获得的主要元素数据相结合，本研究将限制岩石的地幔来源，评估将LSC的演化与Ontong爪哇高原联系起来的假设，并为该地区即将提出的IODP钻探建议做出贡献。该研究的广泛影响包括加强国际合作，培养研究生，以及为IODP科学计划的固体地球目标服务。

Using volcanic rocks to be dredged during an already-funded NSF-ODP program to survey the Louisville Seamount Chain (LSC), the researcher will conduct Nd, Pb, and Sr analyses of 25 samples. By combining the results with major element data being obtained by the already-funded program, this study will constrain the mantle source for the rocks, assess hypotheses that link the evolution of the LSC to the Ontong Java Plateau, and contribute to the pending IODP drilling proposal for this area. Broader impacts of the study include enhancing international collaboration, training of a graduate student, and serving solid Earth objectives of the IODP science plan.
