     Nixiong area in Tibet is geotectonically located in the Ladakh-Gangdise-Lasa-Tengchong land- mass. In the area have been discovered Nixiong large sized rich magnetite deposit and Riar medium sized copper polymetallie deposit etc, Based on stream sediment geochemical survey at scale 1,5 0000 the geo- chemical characteristics and anomly distribution pattern are summarized. Cluster analysis of ore elements shows that mineralization in the area is related to chalcophile elements and iron group elements. Ore-bear ing coefficients of the main strata demonstrate that Permian Angjie formation-and Lage formation are the favorable ore host rocks and Dibucuo formation is the optimum horizon for further exploration of Ag, Zn, Cd, Pb mineral resources in the area. Systematic investigation of mineral resources in the area indicates that geochemical anomlies located are well coincided with the known ore （mineralization） occurrences.
