Abstract

In this study, 115 samples taken from the stream sediments were analyzed for concentrations of As, Co, Cr, Cu, Ni, Pb, W, Zn, Au, Ba, Fe, Mn, Sr, Ti, U, V and Zr. In order to outline mineralization-derived stream sediments, various mapping techniques including fuzzy factor score, geochemical halos and fractal model were used. Based on these models, concentrations of Co, Cr, Ni, Zn, Ba, Fe, Mn, Ti, U, V and Zr showed anomaly and anomaly distributed in the andesitic volcanic rocks. In addition, an anomaly map of each element was also ascertained the most ideal results for the exploration of deposits. Anomaly element associations can be successfully used in future geochemical exploration works. According to stream sediment study, it characterized high anomaly of Ti deposits in the central and northern of the area and it confirmed by study of heavy mineral in sediments and litho-geochemical study in the andesitic unites.
