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.
