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.

探讨了区内造山带演化、金成矿及其动力学机理，提出了热应力是影响变质作用、构造形成演化及成矿地球动力学环境的主控因素的新认识；对多孔均匀介质中流体对流的临界条件进行探讨，首次提出了除岩石物理性质外，构造层厚度和温度梯度是影响流体对流乃至矿质输运的主要因素。
