delineation of enriched zones of mo, cu and re byconcentration-volume fractal model in nowchunmo-cu porphyry deposit, se iran

The purpose of this study is to identify the enriched zones of cu, mo and re in nowchun mo-cu porphyry deposit (se iran) based on subsurface data and using of concentration–volume (c–v) fractal model. the c-v model illustrates four, five and three geochemical zones for mo, cu and re distributions respectively. the main mineralization for mo, cu and re commence from 251 ppm, 0.2% and 2238 ppb respectively, based on the c-v fractal modelling. however, elemental enriched zones contain mo ≥ 501 ppm, cu ≥ 0.4% and re ≥ 4466 ppb. based on a correlation between results obtained by the c-v and geological models, the supergene enrichment zone with cu≥ 0.4% occurs in a small area of ne part at the nowchun deposit within chalcocite accumulation. the enriched zones for mo and re derived via the c-v model are located in the ne, central and sw parts of the deposit. mo and re enriched zones correlate with molybdenite in the deposit.
