ABSTRACT

Recognition of geochemical halos is one of the most important tools for exploration of undiscovered ore deposits. The aim of this study is prospecting for chromite deposits located in the Parang 1:100000 sheet, SE Iran, based on stream sediment data. To do this, geochemical zonality index and Concentration-Area (C-A) fractal modeling were used for chromite prospects determination. Multiplied values of Cr, Co and Ni as the zonality index for prospecting of chromite deposits and various geochemical anomalies were distinguished based on the C-A fractal model log-log plots which indicate four geochemical populations for Cr, Co, Ni and zonality index in the area with low intensive anomalies thresholds of 0.141 ppm, 17 ppm, 77 ppm and 7,943,282 ppm3 respectively. Results obtained by the C-A modeling show that the high intensive anomalies for multiplication of Cr.Co.Ni and Cr are located in the western and central of the studied area. Finally, the result obtained by zonality index and the C-A fractal modeling and Cr anomalies was compared by log-ratio matrix which illustrates that the western and central parts of the area are associated with chromite prospects having a good correlation with the geological model in the Parang 1:100,0000 sheet.
