第九酵母山脊(NER)的构造成因将通过地质学/同位素(Ar/Ar)测量和从7个DSDP和ODP型钻探现场采集的玄武岩样品和2007年从NER采集的23个疏浚样品进行的地球化学(Sr、ND、Hf和Pb同位素)分析来探讨。这些分析将讨论热点的起源，即NER，以及它们是否起源于深部地幔的海脊以下，或者中上地幔或次地圈的更浅的地方。该项目产生的数据将有助于推进热点的地球动力学模型。更广泛的影响：更广泛的影响被认为范围有限，但将为本科生和研究生以及一名由Joi赞助的中学教师提供教育利益和培训。
英文摘要
The tectonic origins of the Ninetyeast Ridge (NER) will be investigated from geochrnonological/isotopic (Ar/Ar) measurements and from geochemical (Sr, Nd, Hf, and Pb isotopes) analyses of basalt samples collected from 7 DSDP and ODP drill sites, and from 23 dredged samples collected from NER in 2007. These analyses will address the origins of hotspots as the NER and if they are sourced beneath the ridge in the deep mantle or more shallow in the mid-upper mantle or sublithosphere. The data generated from this project will help advance geodynamical models of hotspots.Broader impacts: The broader impacts were viewed as limited in scope but will provide educational benefit and training for undergraduate and graduate students, and a JOI-sponsored middle school teacher.
