A study of regional geochemical characteristics of four main genetic types of copper deposits in West Qinling Mountain area shows that there exist very few concentration areas of copper or other elements in 72 copper deposits or occurrences. Based on an analysis of the geochemical environment for the formation of major copper deposits within the distributive area of Bikou Group in southern Gansu, it is held that in West Qinling Mountain area, the indicator elements of various types of copper deposits only reflect the regional geological formations of the corresponding types of copper deposits, whereas the optimal indicator elements reflect ore bearing geological formations. The known copper deposits in the distributive area of Bikou Group and the newly discovered Faziba medium-size copper deposits are all located in the favorable positions indicated by the optimal indicator elements for the eruptive-sedimentary copper deposits of this area.
