PI提出了以南开俯冲带地质条件为约束，建立俯冲带海缘向地震带俯冲推覆的构造模型。其目的是了解从地震到地震过渡过程中的逐步组构发展，提供有助于解释地球物理图像和指导实验实验室研究的信息，并协助解释穿过地震孕育区的钻孔数据。PI将在南开俯冲带的前部使用ODP孔，并在陆地上使用抬升的等效杂岩。
英文摘要
The PI proposes to develop a structural model of the subduction thrust from the seaward edge of the subduction zone through the seismogenic zone with the geological conditions at the Nankai Subduction Zone as a constraint. The objective is to understand the progressive fabric development across the aseismic to seismic transition, to provide information that will help interpret geophysical images and guide experimental lab studies and assist in the interpreting of the drill hole data through the seismogenic zone. The PI will use ODP holes at the frontal part of the Nankai subduction zone and uplifted equivalent complexes on land.
