COPPER AND GOLD MINERALIZATION AND PROSPECTING IN THE DUOBAOSHAN-KUANHE METALLOGENIC BELT,HEILONGJING PROVINCE

The Duobaoshan-Kuanhe metallogenic belt is abundant in copper and gold resources. In early Ordovician, the structural framework was formed with four uplifts and four depressions, which were developed as NE-trending deep fault belts and NW-trending splitting belts and controlled the stratigraphy, magmatism and distribution of minerals in the area. By study on the metallogenic conditions and regularities of the copper and gold deposits, with analysis on the geological background, geophysical and geochemical anomalies and characteristics of the typical deposits within the belt, nine significant targets are located.
