摘要
变异函数是地质统计学的核心内容和基本工具,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.本文在阐述了变异函数理论研究的基础上,依据都龙锡锌矿体的地质特征,运用变异函数,对该矿床Sn、Zn品位进行了变异函数的模拟和结构分析,为该矿床的储量计算和生产勘探提供了科学依据.
Variation function, which is the core and a basic tool of geostatistics, can describe not only the spatial structure change, but also the randomicity change of the regional variable. Moreover its calculation is the foundation of many other calculations of geostatistics. Based on the study of geological characteristics of Sn-Zn ore in Manjiazhai deposit with variogram theory, the grades of Sn and Zn are simulated and structurally analyzed by variation function, which may offer a scientific support for reserves calculation and exploration.
