摘要
八蒙锑矿属断裂—石英脉型矿床,产于前震旦系下江群平略组中上部的绢云母板岩、绿泥石板岩中。本文主要研究了八蒙锑矿含金锑岩石特征,矿物组份,锑矿石的结构、构造类型,围岩蚀变与金锑矿化的关系,提出了金锑矿化的生成阶段。并研究了辉锑矿、黄铁矿及非金属矿物绢云母、绿泥石、石英等含量与特征.除了数十件光薄片鉴定外,还做了人工重砂鉴定,化学、光谱多项分析、物相分析、单矿物分析等测试方法验证。确定了本矿主要以辉锑矿(Sb_2S_3)为特征。金属不可见金,赋存在黄铁矿、毒砂中。此外,对锑矿化、金矿化的成矿条件提出了初步认识.
The Bameng Sb-ore belongs to a fault-quartz vein type deposit,occurring in the sericite slate and chlorite slate the mid-upper part of Xiajiang group, Pinglue formation of Presinian.
This paper mainly deals with Au and Sb-bearing rock features, mineral compositions, types of Sb-ore textures and structures, relations with wall rock alterations and mineralizations of Au and Sb of Bameng Sb-ore. It also studies content and features of antimonite, stibiconite and non-metal sericite, chlorite , quartz, etc. Apart from tne identification of tens of polished -thin slices, the identification of artificial heavy concentrate, chemical analysis, spectral multinomial analysis, object phase analysis and single mineral analysis, etc. have beeh made. It has been ascertained that the ore is mainly characterized by antimonite (Sb2s3) ,with gold invisible in metal and metal existing in stibiconite and arsenopyrite. In addition, a preliminary cognition is advanced about metallogenic conditions of mineralizations of Au and Sb.
