The Qulong Porphyry Copper Deposit is discovered in Tibet,it is one of the significant breakthrough in Chinese geology and exploration works for copper deposits in resent years. The exploration geochemistry play a decisive role in discovering the ore guide of prospecting,ascertaining the genetic types of mineral deposit and evaluating the foreground of prospecting. We circled Cu-Mo mineralization range using regional geochemical anomalies of 1:200000 scale,and ascertained its mineralization types and perspective targets by follow-up anomal survey.We consider that there is geochemical anomaly pattern of typical porphyry copper deposit in the Qulong area,through systematic exploration of geochemistry in the mineral district with the geological and structural data. The degradation level of orebody is very shallow. The Qulong area is a good prospect to looking for supper large-scale copper-molybdenum deposit with the porphyritic type Cu-Mo mineralization as its main ingredient.
