The Opproach to the Material Component and Metallogeny of Denjiashan lead and Zine Deposits

Denjiashan lead and zinc deposits occured between biogenic limestone andphyllite.The mineral source formation was deposited in limited shallowbasin behind the reef under the tide during syndeposition.The industrialore bodies were formed during reformation.Sphalerite and galena are do-minant minerals.Five silverbarring minerals were identified.Besides pband Zn,useful eomponents such and Ag,Cd,Ge,as Ga may be madecomprehensive use of.The essay deseripts the material components and the occuring stateof associated elements of the ore deposits,presents briefly the view onmetallogeny,the research on the ore controls,including stratum,litholo-gical characters,biostrata,lithoracies and structure,and shows that thedeposit belongs to a strata-bound ore deposit of sedimentary and reformative type.
