Orogenic-Type Polymetallic Mineralization Associated with Multistage Orogenesis in Northern North China Plate - 9789811613487

This book focuses on the geological characteristics and genesis of several base metal deposits in the northern margin of the North China Plate, namely the Bainaimiao Cu-Au-Mo, the Huogeqi Cu-Pb-Zn, the Dongshengmiao Zn-Pb-Cu and the Jiashengpan Zn-Pb deposits. These deposits have geological and geochemical affinities with orogenic-type deposits, such as shear zone-controlled mineralization and carbon-rich low-salinitiy ore-forming fluids, and are characterized by multistage ore-forming histories. Remobilization of the pre-enriched (stratabound or porphyry-type) base metals took place as responses to orogenesis and metamorphism, leading to metal redistribution and the formation of orogenic-type orebodies. The formation of orogenic-type base metal deposits is enigmatic, and the case studies presented in this book provide insights into understanding the genesis of this type of deposits. In particular, pre-enrichment of base metals seems to be important, in terms of preconditioning for later shear zone-controlled mineralization, since base metals are believed to have limited solubilities in the low-salinity ore-fluids.
