63 Application of concentration number and concentration volume fractal models to outline mineralized zones in the North Anomaly iron ore deposit BafqAbstractThe North Anomaly iron ore deposit is situated in the Yazd province and Bafq districtwhich is located in 11km NW of Choghart iron ore This study aims to separate thedifferent mineralized zones and the wall rock in the Eastern Central and Western blocks ofthe ore deposit using the concentration number C N and concentration volume C V fractal models The C N model reveals four mineralized zones defined by Fe thresholds of8 21 and 50 with zones 8 Fe representing wall rocks in the Central block TheC V model reveals geochemical zones defined by Fe thresholds of 12 21 43 and57 with zones 12 Fe representing wall rocks The C N model reveals fivemineralized zones defined by Fe thresholds of 8 16 26 and 40 with zones 8 Fe representing wall rocks in the Eest block The C V model reveals geochemical zonesdefined by Fe thresholds of 8 17 and 32 with zones 8 Fe representing wallrocks The C N model reveals four mineralized zones defined by Fe thresholds of 8 20 and 48 with zones 8 Fe representing wall rocks in the Western block The C Vmodel reveals geochemical zones defined by Fe thresholds of 9 20 40 and 47 with zones 9 Fe representing wall rocks Both the C N and C V models indicate thathigh grade mineralization is situated in the central and western parts of the ore deposit Theresults of validation of the fractal models with the geological model show that the C Nfractal model of highly mineralized zones is better than the C V fractal model of highlymineralized zones
