AbstractOne of the copper potential districts in southern khorasan province is known as Dehsalmcopper prospect located 17 kms south of Dehsalm village and was chosen for furthergeological and geochemical exploration to be used for evaluating its potential andfavorability Geochemical studies were conducted through using a square sampling gridof 100 meters for soil covers and 50 meters apart for the fresh rock outcrops To improveand assess the quality of available geological map Aster imagery data were employed todistinguish different rock types based on their different spectral characteristics Due toheavily soil covered surface geology and extensive alteration and erosion imposed on thestudied area we have developed a new spectral matching technique based on least squaremethodology In this regard the main alteration processes normally found on suchvolcano intrusive complexes such as argillic sericitic alunitic iron oxide and propyliticbearing zones were detected using the newly devised image processing algorithm andwas controlled through field and laboratory observations Collecting 1094 soil plus 213rock samples the local geochemical background and anomalous limits were estimatedthrough three basic methods called statistical confidence limit gap statistics and P N statistics Through integrating all available geochemical anomalous maps alteration andgeological features four distinctive zones representing different mineral potentials werefound Utilizing factor analysis of multivariate statistics there found two majormineralization procedures of whom the enrichment of molybdenum in silicified Employing soil geochemical data we have tried the applicability of exploiting elementalpatterns hidden in the data using multifractal power spectrum technique From studyingmultifractality and asymmetry index on various elements it was found that there existsmultifractal patterns in geochemical data and the multifractality index is better suited forthe studied geochemical data
