摘要: Abstract The purpose of this study is to identify the effect ordinary and simple multi-Gaussian kriging (oMK, sMK) estimation methods for delineation iron mineralized zones based on subsurface data using Concentration–Volume (C–V) fractal modeling in Dardevey ore deposit, NE Iran. Spatial analyses (variograms anisotropic ellipsoid) were initially calculated Fe distribution. C–V log–log plots represent various via threshold values. Additionally, variance both was compared. comparison interpretation show that are similar, but enriched highly resulted by oMK have variances lower than sMK method. Furthermore, weakly moderately According variance, optimum values enriched, highly, 56%, 51%, 41% 35%, respectively.
