Identification of Ti-Anomaly in Stream Sediment Geochemistry using Stepwise Factor Analysis and Multifractal Model in Delijan District, Iran
並列摘要
In this study, 115 samples taken from the stream sediments were analyzed to determine the concentrations of As, Co, Cr, Cu, Ni, Pb, W, Zn, Au, Ba, Fe, Mn, Sr, Ti, U, V and Zr. In order to outline mineralizationderived 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 anomalies which are distributed over the andesitic volcanic rocks. In addition, an anomaly map for each element also ascertained the most ideal results for the exploration of deposits. Anomaly element associations can be successfully used in future geochemical exploration projects. According to the stream sediment study, it characterized a high Ti anomaly in central and northern parts of the area which was confirmed by heavy mineral study in sediments and litho-geochemical study in the andesitic unites.
