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.

逆冲断地体的主要问题之一是在其下方的逆冲双相发育过程中盖层如何对应。在弗吉尼亚州南部和西弗吉尼亚州，Keeber砂岩和Tuscarora砂岩被发现在两个环境中。北为盖层序，南为双断陷。该项目将通过阴极发光技术测量这些砂岩的应变，包括石英颗粒的形状变化。研究结果将用于理解盲式双工推力系统与其上覆覆盖物之间的运动相互作用。
