金矿脉分形特征及找矿意义研究

FRACTAL DIMENSIONS OF GOLD-VEIN AND APPLICATIONS IN GOLD DEPOSIT PROSPECTING

摘要: 各种类型的金矿脉常呈不规则的几何形状产出,对它们用欧几里德方法进行描述和分析,不仅难以精确地说明其几何形态特征,有时甚至无法作出实际测量,因此也就很难掌握其产状变化的准确趋势,给金矿床的定量定位预测造成了困难.分形理论为获得有关隐伏矿床(脉)分布的更为准确的信息提供了有利工具.通过对招远灵山和河东两个典型金矿床矿脉分维数、几何丰度和有效紧密度等研究,讨论了分形理论在紧密结合地质特征条件下,客观准确揭示不规则矿脉变化规律及在找矿预测等方面的应用前景.

Abstract: Fractal dimensions of gold-veins were analysed based on fractal dimensions (D), chunkiness (C) and compactness (E) of the gold-veins from different horizations of Lingshan gold deposit. An example for finding gold deposit was given to illustrate good a pplication of geology and fractal dimensions method.
