Collaborative Research: Four-Dimensional Evaluation of a Major Continental Detachment Fault: Structural, Paleomagnetic, and Thermochronologic Constraints

大陆伸展是导致地壳减薄、盆地发育，最终导致大陆分裂、被动大陆边缘和海洋盆地发育的一个基本地质过程。该项目将利用亚利桑那州和内华达州的一个被充分研究的剥离断层来研究正常断层的几个方面，包括相对于位移的下板块的隆起和挖掘历史，以及上下板块作用耦合的程度。这项工作包括综合的构造、裂变径迹和古地磁研究。研究结果有望有助于更好地理解主要的正常断层系统是如何随着时间的推移而演变的。

This project will utilize a well-studied detachment fault in Arizona and Nevada to investigate several aspects of normal faulting including the uplift and exhumation history of the lower plate relative to displacement and the extent to which upper and lower plate processes are coupled. The work involves an integrated structural, fission track and paleomagnetic study. Results are expected to contribute to a better understanding of how major normal fault systems evolve through time.
