Abstract

ABSTRACT This paper endeavours to evaluate the structural controls of porphyry copper mineralization in Dehaj area, Central Iran, using numerical techniques, an aim for which the various data types including the location of mineral deposits, stream sediment geochemical data and faults were employed. Initially, classical statistics and the concentration-area (C-A) fractal methods were applied to identify mineralization-related geochemical anomalies, revealing the superiority of fractal technique over the traditional methods employed. In addition, a rose diagram portraying the distribution of mineral locations was compared to the distribution and trends of faults using fractal and fry analyses, showing that the spatial pattern of porphyry copper deposits is closely linked to NW- and E-trending faults. In other words, the aforementioned structural trends were plausibly the chief geographical directions controlling the mineralization. The results of this study suggest that NW- and E-trending faults have plausibly operated as corridors for the transportation of ore-bearing fluids.

数值技术在斑岩型铜成矿构造控制识别中的应用——以伊朗中部Dehaj地区为例

摘要本文试图利用数值技术评估伊朗中部Dehaj地区斑岩铜矿化的结构控制，目的是利用各种数据类型，包括矿床位置、河流沉积物地球化学数据和断层。最初，将经典统计学和集中区（C-A）分形方法应用于识别矿化相关的地球化学异常，揭示了分形技术相对于传统方法的优越性。此外，利用分形和fry分析，将描绘矿物位置分布的玫瑰图与断层的分布和趋势进行了比较，表明斑岩铜矿床的空间格局与NW和E向断层密切相关。换句话说，上述结构趋势似乎是控制矿化的主要地理方向。这项研究的结果表明，北西向和东向断层似乎是含矿流体输送的走廊。
