A Probe Into the Genesis of Jinding Super-large Lead-Zinc Ore Deposit

The paper prefers to a new genesis model of the Jinding super-large lead-zinc ore deposit,which involved various factors,such as tectonic setting,metallogenic system,genesis of the host rock,metallogenetic epoch and source of ore-forming matter.The deposit was formed during the process of continental collision at Cenozoic.During transtition period from compressed nappe to regional extension in late Eocene to Oligocene(at about 33Ma),fluids with abundant oil gas,salt and metals,sealed in rift or forelandbasin were drived by mantle magma and hot fluid before transition of basin and orogene;arose along the intersection of two groups of extensional structures in the orogence belt;deposited in the structure trap by emplacement of braccia,flowing sand diaper and fluid excretion.
