安徽省东至县—泾县As—Sb—Au矿化带矿物共生组合

Mineral assemblages and the existing form of gold in the As-Sb-Au mineralized belt of the Dongzhi County-Jing County area,Anhui Province

安徽省东至县—泾县As—Sb—Au矿化带中的金矿点分布于从震旦系至奥陶系地层中。不同矿点矿石的矿物组合较为相似,但主要金属矿物黄铁矿、毒砂、辉锑矿含量有明显的差别。 至今有些矿点尚未发现有独立的金矿物,探针分析表明金主要呈次显微金分散于金属矿物中,但不同金属矿物中金的含量并没有明显的差别。

The gold ore localities in the As-Sb-Au mineralized belt of the Dongzhi county-Jing county area,Anhui province are distributed in the Archean-Ordovician strata. The mineral assemblages of different gold ore localities are rather similar, but the contents of major metallic minerals, such as pyrite, arsenopyrite and stibnite are quite different. No individual gold mineral has been discovered in some gold ore localities so far. Gold assumes chiefly the form of sub-micron gold Scattering in the metallic minerals, but there is no obvious difference in gold content in different metallic minerals.
