9530087 Duncan Robert Duncan of Oregon State University is supported to participate in a planned research submersible (R/V Nautile) expedition with French researchers to sample and analyze samples of the deep crust exposed in the Beata Escarpment in the Caribbean Sea. Duncan's work will emphasize the precise dating of samples from the ridge using the Argon-40/Argon-39 technique in which his lab specializes; he will also analyze samples for rare earth elements. The objective of Duncan's research is to test a model based primarily on samples rocks collected on land surrounding the Caribbean that much of the seafloor underlying the Caribbean was formed very rapidly about 88 million years ago by a large volcanic outpouring related to the Galapagos mantle plume. In addition to the specific studies proposed here of samples to be collected by submersible, the project will assist in identifying precise sites for proposed deep ocean drilling by the Ocean Drilling Program, an international collaborative research effort led by NSF using the research drilling vessel JOIDES Resolution. ***

9530087邓肯罗伯特邓肯的俄勒冈州州立大学的支持，参加一个计划中的研究潜水器（R/V Nautile）探险与法国研究人员采样和分析样品的深层地壳暴露在贝亚塔悬崖在加勒比海。 邓肯的工作将强调使用他的实验室擅长的氩-40/氩-39技术对山脊样本进行精确测年;他还将分析样本中的稀土元素。 邓肯研究的目的是测试一个主要基于在加勒比海周围陆地上收集的岩石样本的模型，即加勒比海下面的大部分海底是在大约8 800万年前由与加拉帕戈斯地幔柱有关的大规模火山喷发非常迅速地形成的。 除了这里提议的对潜水器采集的样本进行具体研究外，该项目还将协助确定大洋钻探计划拟议进行深海钻探的精确地点，大洋钻探计划是由美国国家科学基金会领导的一项国际合作研究工作，使用研究钻探船JOIDES Resolution。 ***
