A new understanding of the ore-field structure is proposed. According to the theory of metallogeny by transmagmatic fluid( TMF),it is emphasized that the ore-field structure system is a complexity dynamic system. Based on this model,the ore-field structure deformation is resulted by strong interactions between the near-field and the far-field stress fields. The near-field stress field is induced by the magmatic mineral system instead of the far-field stress field. Accordingly,the regional structure can not be inversed by the ore-field structures,but it could constrain them. The ore-field fractures are often filled by magmatic and / or hydrothermal veins or veinlets,and hence can be recognized. Using the statistic method described in the structure geology,the density map( or contour map) of the magmatic and / or hydrothermal dikes can be used for prognosis of the prospecting targets.
