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

9313596弗雷这个为期三年的奖项支持麻省理工学院的弗雷德里克·A·弗雷和布鲁克塞尔大学的多米尼克·韦斯之间的美比合作研究。这两个小组将对过去4000万年来科尔盖伦火山羽流喷发出的熔岩进行互补的地球化学分析。由此形成的科格伦群岛被认为是地幔“热点”。该奖项为Frey博士的研究生提供旅行支持，以分析和解释补充数据集。这名研究生将受益于美国和比利时导师的专业知识，并可以获得专门的设备。Frey博士为这次合作带来了使用中子活化进行痕量元素分析的专业知识。此外，Weis博士在使用质谱学进行同位素分析方面的专业知识也起到了补充作用。对一段时间内熔岩和火山作用的研究对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了解，更具体地说，将促进我们了解科尔盖伦热点在东印度洋海底形成中的影响。***

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. ***
