MAPPING OF RAW GEOCHEMICAL DATA IN ORDER TO IDENTIFY THE PROMISING AREA IN EAST OF IRAN, SOUTH KHORASAN PROVINCE
Abstract
The main objective of geochemical mapping is to recognize the promising areas for the semi-detailed exploration in next steps of geochemical exploration. To reach the goal the thresholds value of each interested elem ent within the geochemical sample should be determined at the prelimin ary step. At the present article , it is attempted to use the raw geochemical data after pre-processing to distinguish the prom ising area within the Khusf 1:50000 sheets which is located at 35 km west of Birjand at the south khorasan province. This is performed with analyzing of 174 geochemical samples which each of them have been just analyzed for Sb, Fe, Ti, Sr and Sn elements. For each element some maps including of one block map (combinati on of contour and wire frame maps) and image map have been drowned. The concluded results using of this technique shows some anomalies in the study area. Furthermore, it has been drawn that the obtained results are in closed agreement to those acquired with enrichment index methods.
