Detailed study of the tectonic and vocanogenic history of the northrnmost Mariana backarc basin will be performed using existing data from two SeaMARC II side.scan and bathymetric cruises and five Geological ZSurvey of Japan geophysical surveys. Conventional bathymetry, SeaMARC II and seismic reflection data will be analyzed. These data will allow the PI to test models of evolution of the backarc basin spreading systems. Specifically, the PI will examine the tectonic structure of the rift graben; the nature and distribution of volanism in the early stages of rifting; and determine whether the observed structures and volcanic elements agree with those predicted by existing models.

详细研究了青藏高原的构造和火山活动历史， 马里亚纳弧后盆地的最北端将使用 两个SeaMARC II侧面扫描和测深的现有数据 日本地质调查局的五次地球物理调查。 常规测深、SeaMARC II和地震反射数据 将被分析。这些数据将允许PI测试以下模型： 弧后盆地扩张系统的演化。具体地说， PI将检查裂谷地堑的构造结构; 早期阶段沃兰主义的性质和分布 断裂;并确定是否观察到的结构和 火山元素与现有模型预测的一致。
