| Abstract: | Based on metallogenic zoning in the district and 1：200000 stream sediments survey data, this paper made a statistic calculation of background value, average, regional enrichment coefficient and variation coefficient of elements in each metallogenic zone, this paper discussed the background feature, enrichment change, metallogenic feature and element association feature of ore-forming elements and associated elements in the district and each zone, and pointed out major enriched ore-forming elements in the district and each zone. |
