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.
