Based on the data of tectono-geodynamic, stratigraphic, magmatic and mineral resources, the authors present brief characteristics and distribution of endogenous ore formations in the S«ng §µ Structural Zone. From this, we can say that this structural zone is one of riftogenous depression. It was is formed in riftogenous regime and has complicated geological history.

The distribution of endogenous ore formations in the S«ng §µ Structural Zone is described based on the evolution of this depression:

- The pre-forming stage: talc, asbestos...

- The forming stage: Cu - Ni, Cu - polymetal - Au, Cu - Au, Cu - Pb - Zn, Sb, Hg, pyrite, Pb - Zn, Au, Cu.

- The post-forming stage: Cu - Mo, TR, Cu - TR, Cu - TR - Mo, Au, fluorite, barite.
