摘　　要：为给砂宝斯金矿床的勘探和利用提供依据,本文总结了多年的野外观察资料,并通过镜下鉴定、人工重砂、电子探针等方法对该矿床的矿石矿物、金矿物特征进行了系统研究。结果表明,该矿床的矿石类型为贫硫化物微细粒浸染型金矿石,矿石矿物主要为黄铁矿,次为毒砂,含有较多的微量元素;脉石矿物主要为石英。矿石结构主要为半自形-自形、他形、交代、固溶体分离结构,浸染状或细脉浸染状构造。金矿物主要为自然金,其赋存状态以硫化物中包裹金和脉石粒间金为主,主要为微粒金及次显微金,呈微细分散状态。除Au元素外,矿床中其他元素均不具有综合利用价值,有害元素含量低。The Shabaosi gold deposit,which locates in the northern segment of the Daxing’an Mountain,has entered the stage of mine construction and exploitation. This paper studied the characteristics of its ore minerals and gold-bearing minerals on the basis of detailed field geological work,microscopic identification and electron probe analyses. The results showed that,its ores are sulphide-depleted micro-fine disseminated gold ore. The major gold-bearing minerals are mainly pyrite,followed by arsenopyrite,their compositions of trace elements are complex and vary greatly. It suggested that sources of ore-formed materials are complex with obvious hydrothermalism and strong multiple superposition gold mineralization. It indicated that the Shabaosi gold deposit have a good mineralization conditions. Except Au,other elements in the deposit have no need for comprehensive utilization since they are accompanied by harmful elements and since their contents are very low. The gold occurrences are mainly inclusion gold in sulfide and inter-granular gold in gangue,the gold minerals grains are extremely fine,mainly in microscopic and submicroscopic scales.
