Abstract:

Lying in Inner Mongolia, the southern section of  the Da Hinggan Mountains is one of the most important polymetallic belts in China. In this region, mineral deposits are obviously controlled by structures which are mainly folds and fractures. The basic pattern of structures is in NE direction. Mineral deposits (points) are dominantly distributed in the intersections of NE, NNE, NW and EW fractures. They display strongly zoning and gradually changing. The ore bodies disconnectedly distribute along the fractures as irregular veins or lens. The preferable ore-finding areas are the intersections of different directions fractures or the sections of faults where the attitude changed.

Key words: the southern section of , the Da Hinggan Mountains, Cu-polymetallic deposits, ore-controlled structure
