Origin of the Mesozoic Yinshan Fold-and-Thrust Belt of Northern China -- An Enigmatic Intraplate Orogen

远离俯冲带或碰撞缝合线的陆间褶皱冲断带是板块构造理论的难题。 中国北方阴山褶皱冲断带长1100 km，呈东西走向横跨华北板块。 最近的研究揭示了中生代时期主要逆冲断层和一系列挤压事件的存在。 本项目将继续研究阴山带发育的两个样带的几何学、运动学和时间。 结果的目的是在测试是否严重板内变形可以独立发展的外部板块相互作用。

9903012DavisIntercontinental fold and thrust belts located far from subduction zones or collisional sutures present puzzles for plate tectonics theory. The Yin Shan fold and thrust belt of northern China is 1100 km long and trends east-west across the North China plate. Recent work has revealed the presence of major thrusts and a series of compressional episodes during mesozoic time. This project will continue investigation of the geometry, kinematics and timing of Yin Shan belt development in two transects. Results are aimed at a test of whether or not severe intraplate deformation can develop independently of external plate interactions.
