摘　　要：哈图金矿石英中包裹体丰富,个体小,多为3～5μm,包裹体发育不好,反映了包裹体形成时受到了构造的挤压。成矿主要为中温、低盐度。包裹体中水主要为岩浆水,有少量天水的混合。哈图金矿的成矿物质主要为深源。围岩及矿体石英包裹体的稀土元素及碳同位素分析表明成矿流体的稀土元素及矿化剂元素碳的来源与围岩关系不大,哈图金矿的成矿受地层的影响较小。成矿流体的研究显示金矿体向下仍有一定的延伸。There are many fluid inclusions in quartz in the Hatu gold deposit, they are small in size,mostly ranging from 3 to 5μm, and poorly developed, suggesting that they underwent tectonic compression during their formation. The ore deposit formed at middle temperatures and a low salinity. The water in the fluid inclusions is mainly magmatic water with minor meteoric water. The ore-forming material of the deposit was mainly derived from deep sources. REE and carbon isotope analyses of quartz inclusions in wall rocks and orebodies indicate that the source of the REE and the mineralizer elemental carbon has little relation to the wall rocks,and that the mineralization of the Hatu gold deposit was less influenced by strata. The study of ore fluids in the Hatu gold deposit suggests that the gold orebody may still extend downward to a certain depth.
