Crustal Detachment and Destruction of the Keel of North China Craton: Constraints from Late Mesozoic Extensional Structures

Extensional crustal detachment is one of the most important tectonic responses of lithosphere thinning. Late Mesozoic extensional structures, i.e., detachment faults, metamorphic core complexes (mcc's) and fault depression basins, are commonly found in North, South and Northeast China, eastern Mongolia and the Baikal region. The detachment faults associated with these extensional structures may root into either the upper crust (detachment faults...
