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.

PI建议研究从马里亚纳弧前恢复的沉积岩（特别是碳酸盐）的详细沉积学、地球化学和古生物学记录。这些沉积物的历史有助于确定海洋前弧地区的垂直运动历史和构造运动风格。这些信息是必不可少的，因为运动或变形的形式和大小，无论由隆起和下沉的组合，都限制了活动边缘演化的热力学模型。样品将从潜水的ALVIN中收集。
