Abstract

Identification of the vertical and horizontal distributions for elemental grades is of an important sign in different mineral exploration stages. The main aim of this work is to determine the vertical distribution directional properties of Cu values in the Milloieh Cu porphyry deposit, Kerman (SE Iran) using the power-law frequency fractal model. This work is carried out based on four mineralized boreholes. The Cu grade vertical distribution in mineralized boreholes indicates a positively skewed distribution in the former and multi-modal distribution in the latter types. The power-law frequency analysis in nature represents that the Cu values in four mineralized boreholes are bifractal. The two sections of these graphs outline a break point of about 0.5-1% for Cu values and fractal dimension range of 1.70-4.97 in the mineralized boreholes.
幂律-频率分形模型在识别伊朗东南部Milloieh斑岩矿床铜垂向分布中的应用
识别元素品位的垂直和水平分布是不同矿产勘查阶段的重要标志。本工作的主要目的是使用幂律频率分形模型确定伊朗东南部克尔曼Milloieh铜斑岩矿床中Cu值的垂直分布方向特性。这项工作是在四个矿化钻孔的基础上进行的。矿化钻孔中铜品位的垂直分布表明,前者呈正偏斜分布,而后者呈多模态分布。自然界中的幂律频率分析表明,四个矿化钻孔中的Cu值是双分形的。这些图的两个部分概述了矿化钻孔中Cu值约0.5-1%的断裂点和1.70-4.97的分形维数范围。
