In view of the remarkable depletion of such major components as CaO, MgO and Na2O in the drill holes,

in combination with the obvious alteration zoning and the mineralization characteristics of the Wunugetushan

porphyry CuMo deposit, the authors have found that the information of the depletion of CaO, MgO and Na2O in the

drill holes has reflection at surface. In this paper geochemical characteristics of 47 kinds of elements in this

ore deposit were studied. The enrichment and depletion characteristics of these elements as well as the overall

element geochemical features comprising metallogenic elements and such components as CaO, MgO and Na2O are

discussed in detail. In addition, a model for geochemical anomaly structure of the Wunugetushan porphyry CuMo

deposit is put forward. The results obtained by the authors are of great significance in improving and perfecting

the geochemical exploration method and theory for CuMo porphyry deposits.
