The evolution of orogenic zone,gold ore-formation and its dynamic mechanism are studied and the new viewpoint is put forward that thermal stress is a main controlling factor in metamorphism,formation ,evolution of structure and ore-forming geodynamic environment. The critical condition of fluid convection in porous equal medium and the new conclusion is reached first that the thickness of structural layer and temperature gradient are main factors influencing fluid convection andtransport of ore-forming matters in additional to physical properties of rocks. According to the conclusion some mechanisms such as the transform from compressive type to tensile one of erogenic zone,transport and accumulation of ore-forming matters such as gold and so on and many ore-forming temperature values are interpreted qualitatively.
