Presidential Young Investigator Award

PI打算继续研究复杂断层系统的演化。主要的地震地点是圣安德烈亚斯断层在两个非常不同的物理和时间尺度上。在断裂过程中，构造样式的演变以及与每次地震相关的非脆性变形的大小的变化反映了断层表面向非断裂地层的生长所施加的控制，以及旧变形地层的几何形状。在区域尺度上，将填图、构造分析和古地磁研究相结合，了解了横冲和横冲系统如何随时间变化，以及最早的几何构造如何控制应力方向和构造样式的分布。

The PI intends to continue research into the evolution of complex fault systems. Prime field site is the San Andreas fault at two very different physical and temporal scales. During faulting, evolution in the structural style, and the magnitude of nonbrittle deformation associated with each earthquake, changes to reflect the control exerted by growth of the fault surface into unfaulted strata, and the geometry of the older deformed strata. On a regional scale, mapping, structural analysis and paleomagnetic studies are coupled to provide an understanding of how transtensive and transpressive systems change with time, and how the earliest geometry exerts control on the distribution of stress orientation and structural styles.
