A transformation in the tectonic regime affected the continental crust of eastern China during the Middle–Late Jurassic period by changing tectonic trends from E-W to NE and then NNE. The Mesozoic Yanshan tectonic belt in northern China has a distinctive three-segment geometry. This includes a segment south and west of Beijing with a NE trend, a central E-W segment near and east of Beijing, and a NNE-trending segment farther to the east. Field investigations of Mesozoic thrust faults and folds, granitic intrusions and dikes, combined with zircon sensitive high-resolution ion microprobe (SHRIMP) and laser-ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) dating, constrain...
