摘要
The U-Mo 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 U-Mo polymetallic deposits were considered to have genetic relation to the ore-hosted volcanic rocks. On the basis of the in-situ-melting model of granite origin, together with geologic and geophysical features of the Daguanchang U-Mo polymetallic deposit, it is concluded that the Daguanchang U-Mo 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 interface was located at the axial region of the anticline where is suggested to be the optimum locality for porphyry Mo ore prospecting.
