摘要
采用二维地质统计学方法对太平洋ＣＣ区内不同类型金属结核矿区的地质特征进行了定量分析．通过对地质采样数据分析、计算，多角度的实验变差函数对比，建立了丰度、Ｍｎ、 Ｃｕ、 Ｃｏ、 Ｎｉ ５个变量的理想理论变差函数；通过点交叉验证，确定最佳估计参数，建立矿床数学模型：运用克立格方差对其估计结果、精度进行了分析。
Two-dimensional geostatistical method and theory are applied to the quantative analysis of the geological feature of different polymetalloc nodule deposits in the Clarion-Clipperton Zone of the Pacific. We have calculated and contrasted the experiment variograms from various orientation based on geological sampling data and have established the models of theoretical variogram of five variables (abundance, Mn, Cu, Co and Ni ).Through counting cross verification, the best estimated parameter has been determined, the deposit mathematics model has been established and its estimated result and precision have been analyzed with Kriging variance.
