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

PI建议研究详细的沉积学， 地球化学和古生物记录 （特别是碳酸盐）岩石从马里亚纳群岛恢复 前弧 这些沉积物的历史可以帮助确定 大洋垂直运动历史与构造作用样式 弧前区 这些信息是必不可少的，因为风格 以及运动或变形的大小， 的隆起和沉降，限制了热， 活动边际演化的力学模型。 的 将从潜水器ALVIN上采集样本。

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.
