Classification of mineralized veins using concentration volume (C–V) fractal modeling: a case study from Chah-Mesi Cu–Au vein deposit, SE Iran

摘要: The aim of this study is to classify the different Cu–Au mineralized zones based on subsurface lithogeochemical data applying concentration–volume (C–V) model in Chah-Mesi gold–copper vein deposit, SE Iran. C–V modeling identified four geochemical populations (barren host rocks, low, medium, and high zones) for Au Cu log–log plot, which was correlated with veins from geological data. High-mineralized are higher than 2.24 % grade, contain a minor volume mineralization. Main population ranged 0.16 main 0.08 3.54 ppm Au. zone has small extension considered range ppm. results were compared model, showing strong positive correlation between quartz andesite–basalt rocks. To certify this, log-ratio matrix employed validate fractal two lithological units namely andesite––basalt rocks indicating values overall accuracies.
