“…Conventional methods for definition and mapping of different enriched zones in various ore deposits, for example, are based on geological and mine ralogical studies considering variations in the proportions of ore minerals in different type of iron ore deposits (Cox & Singer, 1986;Hitzman et al, 1992). The Kiruna-type iron ores are generally dominated by iron oxides, either magnetite or hematite, which are known to occur in the Kiruna-Gällivare iron province in northern part of the Sweden and in the BafqSaghand iron region in the central Iran (Bonyadi et al, 2011;Shayestehfar et al, 2006;Samani, 1988). Variations of geochemistry and alterations are other useful parameters for identification of variously mineralized zones in Kiruna-type iron deposits (Hitzman et al, 1992;Laznicka, 2005;Sadeghi et al, 2012).…”

Identification of various mineralized zones in an ore deposit is essential for mine planning and design. This study aims to distinguish the different mineralized zones and the wall rock in the Central block of North Anomaly iron ore deposit situated in Bafq (Central Iran) utilizing the concentration-number (C-N) and concentration-volume (C-V) fractal models. The C-N model indicates four mineralized zones described by Fe thresholds of 8%, 21%, and 50%, with zones <8% and >50% Fe representing wall rocks and highly mineralized zone, respectively. The C-V model reveals geochemical zones defined by Fe thresholds of 12%, 21%, 43% and 57%, with zones <12% Fe demonstrating wall rocks. Both the C-N and C-V models show that highly mineralized zones are situated in the central and western parts of the ore deposit. The results of validation of the fractal models with the geological model show that the C-N fractal model of highly mineralized zones is better than the C-V fractal model of highly mineralized zones based on logratio matrix.Keywords: Concentration-Number (C-N); Concentration-Volume (C-V); Fractal models; Iron ore; North Anomaly Identyfikacja stref występowania surowców mineralnych jest kwestia kluczową przy planowaniu wydobycia i projektowaniu kopalni. Celem pracy jest rozróżnienie stref o różnej zawartości surowców mineralnych oraz pasma skalnego w środkowej części zagłębia Bafq (środkowa cześć Iranu) przy wykorzystaniu modeli fraktalnych typu koncentracja-liczba i koncentracja-objętość.

“…Conventional methods for identification and mapping of variously enriched zones in iron ore deposits, for example, are based on geological and mineralogical studies considering variations in the proportions of magnetite, hematite, and apatite, such as in Kirunatype iron deposits (Cox and Singer, 1986;Hitzman et al, 1992;Shayestehfar et al, 2006). The Kiruna-type iron ores are generally dominated by iron oxides, either magnetite or hematite, which are known to occur in the Kiruna-Gällivare iron province in northern Sweden and in the Bafq-Saghand iron district in central Iran (Bonyadi et al, 2011;Cliff et al, 1990;Forsell and Godin, 1980;Frutos and Oyarzún, 1975;Shayestehfar et al, 2006). In this type of iron deposit, magnetite is found at deeper levels compared to hematite.…”
