Quaternary Blind Thrusting in the Southwestern Sacramento Valley, California

本项目在对地震反射资料进行初步分析的基础上，重点研究了萨克拉门托谷地西南部第四系盲冲的模式。这项研究将开发和使用一种基于断层运动学和地表过程之间的相互作用来区分活动断层弯曲和断层传播褶皱的方法。研究结果可望为活动隐伏逆冲构造褶皱样式的识别提供依据，对地震危险性分析和新构造学具有普遍的指导意义。

This project focuses on a model for Quaternary blind thrusting in the southwestern Sacramento Valley based on preliminary analysis of seismic reflection data. The study will develop and use a methodology for distinguishing between active fault-bend and fault- propagation folding based on the interaction between fault kinematics and surficial processes. Results are expected to provide criteria to distinguish fold styles in active blind thrusting, which will be useful in seismic risk analysis and neotectonics generally.
