Mineralization mechanism of the Daguanchang UMo polymetallic deposit and its appli cation in ore prospecting. Earth Science Frontiers , 2 11, 18( 1) :13314 Abstract: The UMo polymetallic deposits located in the Guyuan volcanic basin in the northern rim of northern China terrain attract more and more attentions of geoscientists in China. The UMo polymetallic deposits were considered to have genetic relation to the orehosted volcanic rocks. On the basis of the insit umelting model of granite origin, together with geologic and geophysical features of the Daguanchang UMo polymetallic de posit, it is concluded that the Daguanchang UMo deposit was originated from the activities of porphyries in the deeper localities under the volcanic rocks. It is also proposed that the upheaval domain of the granitic remelting interfacewas located at the axial region of the anticlinewhere is suggested to be the optimum locality for porphyry Mo ore prospecting.
