Abstract
The aim this study is to examine the correlation between Au lithogeochemical anomalies and density of faults utilizing geostatistical analysis, Concentration-Number (C-N) and Concentration-Area (C-A) fractal models in Hizehjan-SharafAbad area, NW Iran. This area is located in the Alborz-Azerbayjan structural zone and Arasbaran metallogenic belt having an Au epithermal type mineralization. In this study, Au variograms, anisotropic ellipse of Au distribution and rose diagram of fault trends were constructed whose analyses showed good correlation between major axis of ellipse with main trend of faults. Consequently, the C-N and C-A log-log plots were constructed for Au and fault-density distributions which revealed very good correspondence/correlation. The results obtained by fractal models indicate a strong correlation between main Au anomalies, anisotropic ellipse major axis and fault-density distributions.
Highlights
A geochemical anomaly occurs by various natural processes related to different geological and mineralization events [1,2,3,4]
The purpose this study is to examine the correlation between Au geochemical anomalies and faults using geostatistical, Concentration-Number (C-N) and Concentration-Area (C-A) fractal modeling in the Hizehjan-SharafAbad, NW Iran
Geostatistical modeling including variography and generation of anisotropic ellipsoid was carried out based on 181 lithogeochemical samples by RockWorks software package
Summary
A geochemical anomaly occurs by various natural processes related to different geological and mineralization events [1,2,3,4]. It may reveal important changes either in geological characteristics and/or mineralization processes. Several methods are used for geochemical data interpretation and modeling such as classical statistics [5,6,7], geostatistical and fractal/multifractal modeling [8,9,10,11,12,13]. The purpose this study is to examine the correlation between Au geochemical anomalies and faults using geostatistical, Concentration-Number (C-N) and Concentration-Area (C-A) fractal modeling in the Hizehjan-SharafAbad, NW Iran
