摘要
本文依据21件黄铁矿样品的电子探针成分分析数据,讨论了Au,Ag,Fe,Co,Ni,S,As,Sb,Cu,Te,Sn,Se等13个元素在黄铁矿中的含量和S/Fe,As/Sb比值在时间和空间上的变化规律。对矿体上的黄铁矿单晶体进行的能谱扫描电镜成分分析,Fe,S,As等成分在黄铁矿内部呈环带状分布,由晶体中心向边缘,它们的含量呈脉动式变化,反映成矿热液活动频繁。
On the basis of the data of electron microprobe analysis of 21 samples of pyrite, we have discussed the values of 13 elements Au, Ag, Fe, Co, Ni, S, As, Sb, Cu, Zn, Te, Sn, Se and thetime-spatial evolutional characteristic of S/Fe, As/Sb ratios in pyrites. By means of energy spectrum analysis to pyrites distributing in the ore-body, it is showed that the district compositional zoning of Fe, Co, Ni content is determined in pyrites. From its center to rim, the compositional zoning of Fe, Co, Ni content changes in pulsation and reflectes that the thermal-fluid activity is very frequent.
