英文摘要	The giant Dongshengmiao Zn-Pb-Cu deposit is located in the Langshan district, northern China The ores are hosted within a Proterozoic rift sequence, which underwent lower greenschist fades metamorphism and shear deformation during development of Early Cretaceous intraplate orogenic belt. Northwest-dipping thrust faults, which share similar orientations and dip angles with the orebodies, are well developed in the mining area. Syngenetic stratabound sulfides were formed during the Proterozoic rifting event, but syngenetic ore textures have seldom been preserved except for some pretectonic fine-grained pyrite. Petrological observation, Ar-39/Ar-40 geochronology, combined with previous isotopic and fluid inclusion studies indicates that significant Zn-Pb-Cu remobilization took place as a result of thrust faulting associated with metamorphic devolatilization of ore-hosting rocks at ca. 136 Ma, coeval with the intraplate orogeny and regional crustal shortening. Sulfides were redistributed in shear structures or along grain boundaries of ore-hosting carbonates, and Fe-rich carbonates were ideal sites for Zn-Pb-Cu precipitation. (C) 2014 Elsevier B.V.
