摘要
狼山-渣尔泰山多金属成矿带位于华北地台北缘西段的中元古代被动陆缘裂陷槽内,其产出的多处大型-超大型铜、铅、锌、铁多金属硫化物矿床的矿床特征具相似性和可对比性。通过分析该成矿带的区域地质背景、含矿建造特征及其产出的典型矿床(东升庙、炭窑口、霍各乞、甲生盘)的矿床地质特征,得出该成矿带内铜铅锌铁多金属硫化物矿床的以下特征:①盆地控矿特征十分明显;②成矿过程中伴有与成矿作用关系密切的同生断裂活动和同沉积期火山活动;③成矿元素具分带性和规律性组合的特征;④各典型矿床具鲜明的"时控"、"层控"和"岩控"特点;⑤成矿作用具有间歇性和多期演化成矿的特征;⑥含矿建造具有典型地球化学剖面结构序列特征;⑦矿体的产状与含矿岩系一致,且相应类型的矿石对应相应的容矿岩性。
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 con- struction 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;（3）the ore-forming elements are assemblaged in zoning and regularity ; （4）the 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 corre- sponding to relevant ore-bearing lithology.
