Collaborative Research: Kinematic Interactions Between Cover and Duplexes

逆冲断层地体的主要问题之一是，在下面的盲冲-逆冲双重开发过程中，盖层如何对应。在弗吉尼亚州南部和西弗吉尼亚州，基伯砂岩和塔斯卡罗拉砂岩在两个背景下被发现。北侧为盖层序，南侧为双重断裂。该项目将测量这些砂岩中的应变，包括利用阴极发光技术测量石英颗粒的形状变化。研究结果将用于理解盲式双力推力系统与其覆盖层之间的工作运动学相互作用。

One of the major questions in thrust fault terranes is how the cover corresponds during blind-thrust duplex development below. In southern Virginia and West Virginia, the Keeber and Tuscarora Sandstones are found in two settings. To the north they are in the cover sequence, and to the south they are involved in duplex faulting. This project will measure strain in these sandstones, including shape changes in quartz grains by cathodoluminescence techniques. Results will be applied to understanding the operative kinematic interactions between a blind-duplex thrust system and its overlying cover.
