摘　　要：为研究黑龙江省漠河地区潮满林场768高地银铅矿床成矿流体特征及成因,通过流体包裹体显微测温并结合该矿床地质特征,探讨其成因。结果表明:该矿床赋存于晚石炭世花岗岩中,与早白垩世中酸性脉岩关系密切,可划分为黄铁矿-石英、多金属硫化物-石英、少硫化物-碳酸盐三个阶段;该矿床以硅化、黄铁矿化、黄铜矿化、闪锌矿化、方铅矿化及绢云母化等中低温矿化蚀变为主;矿床的流体包裹体类型仅有气液两相型,为中低温中低盐度的H_(2)O-NaCl体系热液。综合分析认为,早白垩世中酸性侵入岩与成矿关系密切,矿床成因为中低温岩浆热液脉型。This paper is intended to investigate the metallogenic fluid characteristic and genesis of silver lead deposit in 768 highland of Chaoman forest farm in Mohe region,Heilongjiang Province.The study works by fluid inclusion microthermometry together with the geological characteristics of the deposit.The results show that this deposit occurs in Late Carboniferous granite closely related to the early Cretaceous intermediate-acid dyke.It can be divided into three stages of pyrite-quartz,polymetallic sulfide-quartz and less sulfide-carbonate.The deposit is mainly characterized by medium-low temperature mineralization and alteration,including chalcopyrite,galena,sphalerite,pyrite,silicification,sericite mineralization and so on.The fluid inclusion type of the deposit is only gas-liquid two-phase inclusions which is the H_(2)O-NaCl hydrothermal solution with the medium-low temperature and medium-low salinity.Based on the comprehensive analysis,the mineralization is directly related to the early Cretaceous intermediate-acid intrusive rocks,and the deposit belongs to the medium-low temperature magmatic hydrothermal vein type.
