摘要
变异函数是地质统计学的核心和基本工具。它既能描述区域化变量的空间结构性变化,又能描述其随机性变化,变异函数分析是许多其它地质统计学计算的基础。文章在阐述了地质统计学原理和变异函数理论研究的基础上,运用Surpac矿业软件,根据都龙锡多金属矿床主矿体的产出特征,对该矿区锡、锌品位进行了变异函数分析,并对分析结果进行了地质解释。
Variogram is the core and basic tool of geostatistics, and can describe spatial structure and random changes of regional variable. Variogram a- nalysis is the foundation of many other geostatistic calculations. Using Surpac software and based on occurrence of main ore bodies in the Dulong tin polymetallic deposit, Variation function of tin and zinc grades is analyzed, and results are explain geologically.
