One of the basic concepts of Plate Tectonics is that continental plates are rigid, with deformation only along their margins. However, there are extensive areas within continental crust that have undergone large magnitude distributed deformation at a regional scale, notably in the southwestern United States. This project will use a combination of field and laboratory techniques to evaluate the role of strike-slip faulting and block rotation and measure the internal deformation of a portion of the Basin and Range province, and to attempt to relate this deformation to plate boundary processes.

板块构造学的一个基本概念是大陆板块是刚性的，只在其边缘发生变形。然而，大陆地壳内部也有广泛的区域经历了大震级的区域性分布变形，特别是在美国西南部。该项目将结合现场和实验室技术来评估走滑断层和块体旋转的作用，并测量盆地和山脉省部分地区的内部变形，并试图将这种变形与板块边界过程联系起来。
