摘要:
近年来，在全国“358”找矿突破战略行动中，八宝山矿区深部铁铜多金属矿普查取得找矿突破，提交一中型铜矿床，且钼探矿取得找矿新突破。通过对八宝山矿区成矿地质背景、深部矿床地质特征的研究，认为矿体类型可分为矽卡岩型铁铜矿体（接触带）、斑岩型铜钼矿体（内接触带）、热液型铅锌银矿体（外接触带）。综合区域成矿背景、矿区成矿过程、深部矿体特征，讨论了深部找矿前景，认为53勘探线、55勘探线、2勘探线和4勘探线深部为北-Ⅲ铜钼矿体找矿有利地段，19勘探线、55勘探线和2勘探线深部为南-Ⅴ钼矿体找矿有利地段；南矿带向北侧伏，北矿带向南侧伏，南、北矿带深部-700～-500 m标高可能会形成“v”形容矿构造，产生富矿层位。此次研究对区域上类似铁铜多金属矿床找矿具有一定借鉴意义。

Abstract:
In recent years,in the national 358 prospecting breakthrough strategic action,prospecting breakthrough has been made in the general survey of iron copper polymetallic ores deep in Babaoshan Mining District,a medium-sized copper deposit submitted.Besides,molybdenum ore prospecting has made new breakthrough.Based on the study of metallogenic geological background and geological characteristics of deposits deep in Babaoshan Mining District,it takes that the ore body type can be pided into skarn type iron copper ore body(contact zone),porphyry copper molybdenum ore body(inner contact zone) and hydrothermal lead zinc silver ore body(outer contact zone).The metallogenic background,ore-forming process in the mining district and ore body characteristics in the deep part are comprehensively considered,and the prospecting prospect deep in the district is discussed,finding that deep in explora-tion line 53, 55, 2 and 4 are favorable prospecting sections for North-Ⅲ coper molybdenum ore bodies and deep in exploration line 19,55 and 2 are favorable prospecting sections for South-V molybdenum ore bodies; the south ore belt trends laterally north while the north ore belt trends laterally south,likely leading to v-shaped ore-hosting structure formed by the south and north ore belts at -700--500 m elevation and generating strata rich in ores.The research provides certain reference for prospecting similar iron copper polymetallic deposits in the district.
