在深入研究矿床地质和矿化特征的基础上,查明黄铁矿中Co、Ni的分布特点可为研究矿床成因和成矿作用提供重要信息.本文收集7个与古海底火山活动有关的铁铜矿床黄铁矿中Co、Ni含量资料(表1),并计算了Co/Ni比值、平均值及Co/Ni比值的均方差(表2). 从表1、表2可得出以下几点: 1.所列矿床单个黄铁矿样品的Co/Ni比值绝大部分大于1,仅个别小于1,但平均值均大于1.
Based on the in-depth study of the geological and mineralization characteristics of the deposit, it is important to find out the distribution characteristics of Co and Ni in the pyrite so as to provide information for studying the genesis and mineralization of the deposit. Copper content of pyrite in the copper ore (Table 1), and calculated the Co / Ni ratio, the average and Co / Ni ratio of the mean square deviation (Table 2) can be drawn from Table 1, Table 2 can be drawn from the following When: 1. The individual pyrite samples listed in the deposit are mostly Co / Ni ratio greater than 1, only less than 1, but the average value is greater than 1.
