Abstract
In this research work, the fractal modeling of Au anomalies in the Chaapaan 1:100,000 sheet (NW Iran) is conducted through an investigation of the concentration-distance to lineament (C-DL) relationship. The classification of Au anomalies is based on their proximity to major lineaments. Stream sediment data is utilized to identify Au anomalies, and the C-DL model demonstrates a strong correlation between the main gold anomalies and their distance from remote sensing lineaments. The findings indicate that gold anomaly values exceeding 12 ppb are found within a distance of less than 1 km from the remote sensing lineaments, establishing a significant association between fault structures and mineralization. Moreover, the average distances to remote sensing lineaments are found to be less than 1.3 km, underscoring the suitability of the C-DL fractal modeling for identifying hydrothermal gold deposits.
