Abstract: Two types of multifractal modes are generalized from Cu, Pb, B, Ti in 1∶50000 stream sediment survey in Bileti area of Xinjiang. The power-law diagram of mode one and mode two are fitted by two straight lines and three straight lines respectively. Elements of mode one are distributed as background and regional anomalies, which show no significant enrichment and ore-forming potential. Elements of mode two have strong local anomalies with fairly promising prospecting potential in addition to the background and regional anomalies. Four prospecting targets for Cu, Pb polymetallic minerals are delineated based on geochemical and geological characteristics in this area.
