Late Jurassic‐Early Cretaceous Deformation in the Western Yanshan Fold‐Thrust Belt: Insights From Syntectonic Sedimentation in the Chicheng Basin, North China

The Yanshan fold‐thrust belt is a significant intraplate deformation belt along the northern margin of North China Craton and records multiple phases of deformation during the Mesozoic. However, the specific tectonic evolution of the Yanshan belt during the Mesozoic has long been debated. In particular, many arguments exit regarding whether a contractional or extensional context dominated the Yanshan belt in the Late Jurassic‐Early Cretaceous....
