Three-Dimensional Kinematics of Fold-Thrust Belt Salients at Two Scales: Sierra Madre Oriental, Mexico

小行星9614582 褶皱和冲断带是碰撞构造的结果，很少是直的。 造山带中不同尺度上的凸起和凹陷可能是不同机制的结果，但其发育的三维运动学序列通常难以确定。 本项目将研究马德雷山脉东方褶皱冲断带的两个凸起，初步信息暗示了显著的横向运动学变化，可能有两种不同的形成机制。 这些突出物异常暴露良好，预计将为严格的建模提供足够的控制。 研究结果将有助于阐明形成复杂的三维弯曲褶皱冲断带的过程。

9614582 Marrett Fold and thrust belts the result of collisional tectonics, are seldom straight. The salients and recesses observed on several scales in orogens may be the result of different mechanisms, however it is commonly difficult to determine the three-dimensional kinematic sequences of their development. This project will examine two salients in the Sierra Madre Oriental fold-thrust belt where preliminary information hints at significant across-strike kinematic variation, and probably two different mechanisms of formation. The salients are unusually well-exposed, and are expected to provide adequate controls for rigorous modeling. Results should help clarify the processes that give rise to the three-dimensional complexities curved fold-thrust belts.
