A Study of the Strain Variation and Rheology in an Internal Thrust Sheet, Sheeprock Mountains, Utah: Implications for Fold-and-Thrust Belt Evolution

小行星9418688 逆冲岩席是许多褶皱-冲断带的腹地部分，它们往往比那些位于更外侧位置的岩席更大，并显示出更大的位移，似乎在变形过程中控制着褶皱-冲断带的整体锥度。 这个项目将使用空间统计学来研究希普洛克逆冲岩席内的应变变化模式，以了解这些大岩席的几何形状和变形历史，并评估临界楔理论所暗示的驱动力。 研究结果对许多褶皱冲断带具有一定的适用性。

9418688 Mitra Thrust sheets is the hinterland portion of many fold-and-thrust belts tend to be larger and show larger displacement than those in more outboard positions and appear to control the overall taper of a fold-thrust belt during deformation. This project will examine the strain variation pattern within the sheeprock thrust sheet using spatial statistics in order to understand the geometry and deformational history of these large sheets, and to asses the driving forces that are implied by the critical wedge theory. Results will be applicable to many fold-thrust belts.
