摘要/Abstract

摘要： 以烟筒砬子铜金矿区ZK001元素垂向分带序列的计算为例，对格里戈良分带指数法进行了两个方面的改良：在原始数据换算中，采用正规化法将原始数据变换为\[0，1\]区间的数值，避免了传统方法的人为因素，减少了计算量；在计算分带指数的变化梯度时采用原格氏法变化度的倒数，解决了原格氏法计算中可能出现的某一层位的分带指数为零则无法计算的问题。新旧两种格氏法计算结果相比，新方法更符合实际地质情况。

Abstract: The text takes the calculation of elemental vertical zoning of ZK001 in Yantonglazi Cu-Au deposit as an example, puts forward two improved aspects of calculating the Gregorian’s zoning index: in preparing the original data, normalization method of cluster analysis is used to get data format of \[0,1\] for deceasing calculation and for avoiding some manmade error; in calculating the variation degree, the reciprocal of the variation degree from traditional Gregorian’s zoning index method is used to represent the variation degree. This improvement can solve the problem that sometimes calculation cannot be carried out when some zoning index are zero. The calculation result by the method present here seems to match the geology in study area better than that by traditional Gregorian’s zoning index calculation method.

Key words: Gregorian’s method, zoning sequence, zoning index, variation degree
