Abstract
Langshan-Zha'ertaishan polymetallic deposit is located in Mesoproterzoic passive continental margin rift trough within west section of the northern edge of North China Platform,where many large-scale-super large-scale Cu,Pb,Zn,Fe polymetallic sulfide deposits are characterized by similar and comparable features.According to analyze the regional geological background of the ore-forming belt,ore-bearing construction characters and geological characteristics of typical deposits occurred there(Dongshengmiao deposit,Tanyaokou deposit,Huogeqi deposit,Jiashengpan deposit),the study has concluded the following features about the Cu-Pb-Zn-Fe polymetallic sulfide deposit: ① the obvious characters about basin controlling the ores;② the ore-forming process was associated with the activities of contemporaneous faults and codeposition volcanic movements that area closely related to mineralization;③the ore-forming elements are assemblaged in zoning and regularity;④the kinds of typical deposits are characterized by clear time-bound,strata-bound and rock-bound features;⑤ the mineralization is characterized by intermittent and multi-stage evolution;⑥ the ore-bearing construction is typically represented by structure sequence of geochemical profile;⑦ the occurrence of orebody is consistent with ore-bearing rock series,with corresponding kinds of ores corresponding to relevant ore-bearing lithology.
