内蒙古地区十一站金矿床地球化学特征研究

A study on geological and geochemical feature of Shiyizhan gold deposit in Neimenggu

通过内蒙古地区十一站金矿床地球化学场特征的研究,发现其矿床物质来源于上元古界和寒武系变质岩,华力西期花岗岩为矿体形成提供了热源,北西向、北东向断裂及断裂破碎带是矿体赋存的有利部位。其地球化学特征为,含矿岩系富集Au,As,Sb,Ag,Pb,Cu等主要成矿元素,并有多个元素组合伴生,而且异常规模大、强度高,矿体位于主要成矿元素异常集中区。

Shiyizhan gold deposit is one of the deposits discovered by the author et al. studies of geochemistry information of this region.The metallo genetic materials come from the metamorphic rook of Proterozoic Eon and Cambrian periods Granite of Hualixi period provides the heat sources for the formation of ore bodies.Northwest northeast faults and fractures are preferred places to keep ore bodies. The geochemistry features specifically show that original rocks of containing minerals concentrate Au,As,Sb,Ag,Pb,Cu etc elements which are composed of the abnormality of element combinations and are several,and the scale of abnormality is great, the strength is high, the central zones of anomaly are ore bodies. These features are very typical.
