U.S.-Belgium Cooperative Research: Temporal Geochemical Variation of Lavas Erupted from the Kerguelen Plume (0-40 Million Years)

小行星9313596 这个为期三年的奖项支持美国-比利时合作研究弗雷德里克A。马萨诸塞州理工学院的Frey和布鲁塞尔自由大学的Dominique Weis。这两个小组将对过去4 000万年来凯尔盖朗火山柱喷发的熔岩进行补充地球化学分析。由此形成的凯尔盖朗群岛被认为是地幔“热点”。“该奖项为弗雷博士的研究生提供旅行支持，以分析和解释补充数据集。 研究生将受益于美国和比利时导师的专业知识，并有机会获得专业设备。 Frey博士为这次合作带来了使用中子活化进行微量元素分析的专业知识。 Weis博士在使用质谱法进行同位素分析方面的专业知识对此进行了补充。 对一段时间内的熔岩和火山活动的研究对于了解地幔热点非常有用。Frey和Weis建议将这种方法应用于Kerguelen群岛的熔岩。他们的研究将促进我们对地幔热点的理解，更具体地说，是对凯尔盖朗热点在形成东印度洋海底方面的影响的理解。 ***

9313596 Frey This three-year award supports U.S.-Belgium cooperative research between Frederick A. Frey of Massachusetts Institute of Technology and Dominique Weis of the Universite Libre de Bruxelles. Both groups will perform complementary geochemical analyses of lavas erupted from the Kerguelen volcanic plume over the last 40 million years. The resulting Kerguelen Archipelago is considered a mantle "hotspot." The award provides travel support to Dr. Frey's graduate student for analysis and interpretation of the complementary data sets. The graduate student will benefit from the expertise of U.S. and Belgium mentors and have access to specialized equipment. Dr. Frey brings to this collaboration expertise for trace element analysis using neutron activation. This is complemented by Dr. Weis' expertise in isotopic analysis using mass spectrometry. Studies of lavas and volcanism over a period of time have been very useful in understanding mantle hotspots. Frey and Weis propose to apply this approach to the Kerguelen Archipelago's lavas. Their study will advance our understanding of mantle hotspots and more specifically, of the Kerguelen hotspot's influence in creating the eastern Indian Ocean seafloor. ***
