COLLABORATIVE RESEARCH: 3-D Kinematic Evolution of the Charleston-Nebo Salient, Sevier Fold-Thrust Belt

褶皱冲断带几何学的一个基本方面是存在弧形凸起，其中逆冲痕迹向运输方向广泛凸起。虽然理论和物理模拟模型描述了逆冲带凸起的总体发展，但对凸起的三维运动学和变形速率了解很少。该项目将测试现有的显著开发模型，并利用犹他州中北部塞维尔褶皱冲断带的查尔斯顿-内博凸起开发新模型，该模型保留了异常良好的运动学历史，没有后续的叠印。预计这一结果将使人们更好地了解逆冲带突出环境中的运动学历史和变形速率。

9903105DeCelles A fundamental aspect of fold-thrust belt geometry is the presence of curved salients in which thrust traces are broadly convex towards the transport direction. Although theoretical and physical analog models describe the general development of thrust belt salients, the 3-D kinematics and rates of deformation in salients are poorly understood. This project will test existing models of salient development and develop new models using the Charleston-Nebo salient of the Sevier fold-thrust belt in north-central Utah, which preserves unusually well kinematic history without subsequent overprinting. It is anticipated that the results will yield greater understanding of the kinematic history and rates of deformation within a thrust belt salient environment.
