Petrologic and Geochemical Studies of Mariana Forearc Sediments Collected by Dredging and the Submersible Alvin

PI建议研究从马里亚纳弧前恢复的沉积(特别是碳酸盐)岩石的详细沉积学、地球化学和古生物记录。这些沉积物的历史有助于确定大洋弧前地区的垂直运动史和构造样式。这一信息是至关重要的，因为运动或变形的方式和大小，无论是抬升还是下沉的组合，都限制了活动边缘演化的热和力学模型。样本将从阿尔文号潜水器上采集。

The PI proposes to study the detailed sedimentological, geochemical, and paleontological record of sedimentary (particularly carbonate) rocks recovered from the Mariana forearc. The history of these sediments can help determine the history of vertical motion and styles of tectonism in oceanic forearc regions. This information is essential because the style and magnitude of movement or deformation, by whatever combination of uplift and subsidence, places constraints on thermal and mechanical models for the evolution of active margines. The samples will be collected from the submersible ALVIN.
