The theory of dissipative structures is applied in this paper to probing into the dynamics, temporal struc-tures and spatial structures of ore-forming processes and the inherent relationships among them. Areas of oreformation are large dynamic systems in development and evolution. The core of ore formation is the "onset ofore-forming processes". and the crux of it is the "transition from mineralization to ore formation". The theoryof bifurcation and theory of fluctuation make possible the access to the solution of this problem. The multiord-er or successive bifurcation of dissipative structures introduces dynamic geochemical processes into geosciencesand inverses the dynamic evolution and temporal rhythms of ore-forming processes. The localization ofdissipative structures introduces dynamic geochemical fields into geosciences and brings to light the causes andmechanisms of the formation and development of geochemical areas of ore formation (regions and zones of oreformation) and their spatial dynamic patterns.
