Abstract The Harlik metallogenic belt is a favorable area for polymetallic mineralization of Cu,Au, W, Sn, Mo, Fe, Mn, Ni and Co. In order to further study the ore-bearing properties of each stratum in the metallogenic belt, based on the 1:50 000 stream sediment measurements in Hami area of Tianshan Mountains, the authors analyzed the characteristic parameters, distribution and evolution of 17 elements, and the ore-bearing properties of 7 stratigraphic units. The results show that Au, Sb and Bi are of extremely uneven distribution (C_v≥1.5), and As, Hg and W are of uneven distribution (1.5>C_v≥1.0). There are four distribution types of elements in the region: symmetry, positive bias, negative bias and bimodal. The concentration coefficients of these elements and oxides show a wavy and tortuous change in each stratigraphic unit. Iron group elements are mainly enriched in Daliugou Formation and Tousuquan Formation. Tungsten and molybdenum group elements are mainly enriched in Tousuquan Formation. Au is mainly enriched in Daliugou Formation and Dananhu Formation. Au, Cu, W, Bi, Fe, Mn and Zn are the dominant mineral resources in the study area after comprehensive analysis. And the main mineralizing elements are Au, Cu and Fe, and their optimum enrichment age is Ordovician, followed by Devonian. The Daliugou Formation of Ordovician is the main ore-bearing stratum.
