Characteristic of silstone copper ore in Tianlu copper deposit

Tianlu copper deposit which formed by foreland basin in Paleozic era is marine sandshale copper deposit,copper ore mainly is silstone type and in cludes six natural type,which are chalcocite ore,chalcocitebornite ore,bornite ore,chalcopyrite-bornite ore,chalcopyrite,pyrite-chalcopynite.Ore texture mainly is crystallzation texture and metasomatic texture.Ore structure are dominated by disseminate.Along thickness of strata,mineralization of master ore bed has obviously vertical zonality in the upward order of chalcocite→bornite→chalcopy rite→pyrite,It is indicated that typical arrangement assemblage feature of sulphide of sediment orogenic copper ore.Abovementioned cha racteristic is consistent to marine sand shale copper deposit in china and foreign.
