Mineralization, Geological Features, and Prospecting Indicators of the Copper(Molybdenum) in Southern Margin of Taibai Rock-Mass

In the southern margin Taibai rock-mass,the copper(molybdenum)ore has been found.There are 2 copper ore bodies,one copper-based body and 5 molybdenum mineralized bodies.The length of the Copper ore body is 245～445 m,with an average thickness of 2.03～2.81 m and an average grade of 1.57% to 1.67%.The length of molybdenum mineralized body is 50m,with a thickness of 2.03～2.81 and a grade of 0.01%～0.54%.The mineralizattion of copper-molybdenum is controlled by three factors: rock,structure,and alteration.We use the mining ore molybdenite Re-Os method to testiso topic age and obtain the age of 119.3～123.7 Ma for the copper-molybdenum mineralization in this area formed in the late Yanshan.
