Integration of Fractal Geometry and Correspondence Analysis Geochemistry Methods to Reconnaissance High-Potential Promising Areas in a Field of NE Iran

Abstract

Abstract The background Anomaly separation is one of the essential stages in geochemical explorations. Most geochemical and geostatistical works in mining exploration aim to identify an anomaly better based on scientific discussions. In this paper, Integrating the correspondence analysis and fractal method, the results of analysis data for river sediment sampling at the Khusf area in NE Iran have been investigated. Correspondence analysis with 170 data samples and 20 elements was done. According to correspondence analysis, separating one or several elements is the reason for anomalous value in the study area. Separating one or several samples is the reason for the aimed elements at the studied samples. The results of seven samples show the highest concentration relative to the variables Pb, As, and Cd elements. The correspondence analysis results show that the Khusf area at some locations for Pb, Cd, and as elements have been probability anomalous. After the correspondence analysis, the best variogram for the Khusf area using Win_Gslib software was obtained. The obtained variogram and designed network for estimation by the kriging method at the mentioned area was used. Therefore using the fractal method, three statistical sets determined that the third set showed the anomaly for Pb, Cd and As elements nearly. The separation value, respectively, determined about 55, 7.2, and 0.88 ppm. Finally, it is suggested that this region has the potential of essential metals, especially of the above elements, and will carry out geophysical operations on a local identification scale.
