目前,对热液型多金属硫化物的矿物共生组合还缺乏定量解释。本文以回归分析方法处理 J_2矿二号矿体的地质资料,获得了因变量金与变量铁、锌、铅的相关关系。在此基础上,我们将统计结果运用于二号矿体外围的地质工作,得到予期的效果。现已查明,J_2矿为一大型的、以金银为主的硫化物矿床。这种探索在 J_2矿——这个具体地质条件下的热液型多金属硫化物矿床——是成功的,对研究本类型的其他矿床矿物共生组合规律、成矿过程也很可能有所裨益。
At present, there is a lack of quantitative explanation for the mineral assemblages of hydrothermal polymetallic sulphides. In this paper, the geological data of No.2 ore body of J_2 mine is processed by regression analysis, and the correlation between the dependent variable gold and the variables iron, zinc and lead is obtained. On this basis, we apply the statistical results to the geological work on the periphery of No.2 ore body, and obtain the expected results. It has been identified, J_2 mine is a large, gold and silver-based sulfide deposits. This exploration is successful in J 2 mine, a hydrothermal polymetallic sulphide deposit under this specific geological condition, and it is quite possible to study the mineralization and symbiosis of other ore deposits of this type.
