Abstract
According to the basic geology study, the feature of the element association and the analysis on characteristic element abnormal combination, we think that there are large scale intermediate-basic volcanic (subvolcanic) rocks with some medium acid intruded rocks or vein rocks groups by the work of 1 to 50000 scale geochemical exploration in the north Sanjiang-Wenquanbingzhan area. The fractures of Yanshiping and Wenquanbingzhan area etc. are the big fractures of guide rock and rock-controlled and the fracture zones in the northwest of Chuduo-Chaqiong play an ore conducting and controlling role in the process. The metallogenic condition of anticline structure is better than that of syncline structure. Based on the above consideration, the diagenesis and mineralization in this area are closely related to the intermediate-basic and acidic magmas activity. Copper and polymetallic ores can be classified to volcanics-type and sedimentary-reformed type.
