秩相关权法及其在资源靶区定位预测中的应用

RANK CORRELATION WEIGHT METHOD AND ITS APPLICATION TO LOCATIVE PREDICTION OF RESOURCES TARGETS

提出了一种矿产资源靶区定位预测的统计方法秩相关权法。该方法以评价目标变量（矿床的资源量、矿床规模等）与成矿和控矿地质变量（定量地质变量、半定量地质变量和定性地质变量）之间的秩相关性研究为基础，用地质变量与目标变量之间的τ秩相关系数来衡量地质变量的重要程度。

The authors of this paper proposed a new statistical method so called rank correlation weight method used for locative prediction of mineral resources targets. This method is based on rank correlation of objective variables (quantity of mineral resourcs, metallogenic size, etc.) and metallogenic or ore-controlling geological variables (quantitative geological variable, qualitive variable and semiquantitative variable). The signiticances of geological variables are measured by τ -rank coefficients of geological variables and objective variable. The potentials of mineral resources targets are measured by relativities of ore deposit cells.
