Abstract:Based on processing of data obtained from 1:25 000 stream sediment survey in Gahe River area, the authors delineated anomalies of such elements as Cu, Pb, Zn, Ag, Au, As, Sb, Cr, Ni and Co, detected the distribution characteristics of the anomalies in the study area, evaluated the ore-prospecting significance of the anomalies, and determined the element association. In combination with the metallogenic geological background and according to the geochemical composite anomalies and association features of mesothermal-epithermal elements, four perspective areas in search for Pb, Ni and Ti deposits were determined, from which No. 3 Pb target area and No. 4 Ti and Ni key target area were delineated through optimization.
