Abstract

The Baneh- Saqqez zone is part of the Sanandaj‒Sirjan Zone, northwest of Iran. Generally, this zone is recognized as a gold bearing zone, and the mineralization in it is controlled by faults. In this research, structural lineaments were extracted using Landsat 8 (OLI) image, in which the main lineaments trend NE‒SW, EW and NW‒SE. Spatial distributions of the mineralization are examined by using the point pattern, Fry and fractal analyses. The pattern of structural controls on the gold mineralization in southwest Saqqez, is almost regular, and the trend of gold mineralization and Fry points show NE‒SW and EW trends. Comparison of rose diagrams for the Fry analysis final translation points and faults in southwest Saqqez show that the orientations of mineralization are similar to NE‒SW and EW trending faults and that the mineralization intersects the NW‒SW trending faults. The results of fractal analysis suggest that gold occurrences in the area have higher fractal dimension. The deep regional faults cause a way for ore-bearing fluids to migrate and control the emplacement of the intrusive bodies and the position of ore mineralization in the Saqqez‒Baneh sub-zone. On that basis, a survey of spatial data and its relationship to structural features can be useful for future exploration and discovery of new occurrences of gold mineralization.

点状,油炸和分形分析在西南萨克兹地区金矿化空间分析

摘要

Baneh-Saqqez地区是伊朗西北部Sanandaj‒Sirjan地区的一部分。通常,该区域被认为是含金区域,其矿化受断层控制。在这项研究中,使用Landsat 8(OLI)图像提取了结构线,其中主要线趋势为NE‒SW,EW和NW‒SE。通过使用点模式,Fry和分形分析来检查矿化的空间分布。萨克兹西南部的金矿化结构控制模式几乎是规则的,金矿化趋势和弗莱点显示出NE‒SW和EW趋势。萨克兹西南部的Fry分析最终平移点和断层的玫瑰图比较表明,矿化的方向与NE‒SW和EW趋势断层相似,并且矿化与NW‒SW趋势断层相交。分形分析结果表明,该地区金矿的分形维数较高。较深的区域性断层为含矿流体的迁移和控制侵入体的位置以及萨克奇兹·贝纳(Saqqez‒Baneh)子区的矿化位置提供了一种途径。在此基础上,对空间数据及其与结构特征的关系进行的调查对于将来的勘探和发现新的金矿化可能是有用的。分形分析结果表明,该地区金矿的分形维数较高。较深的区域性断层为含矿流体的迁移和控制侵入体的位置以及萨克奇兹·贝纳(Saqqez‒Baneh)子区的矿化位置提供了一种途径。在此基础上,对空间数据及其与结构特征的关系进行的调查对于将来的勘探和发现新的金矿化可能是有用的。分形分析结果表明,该地区金矿的分形维数较高。较深的区域性断层为含矿流体的迁移和控制侵入体的位置以及萨克奇兹·贝纳(Saqqez‒Baneh)子区的矿化位置提供了一种途径。在此基础上,对空间数据及其与结构特征的关系进行的调查对于将来的勘探和发现新的金矿化可能是有用的。
