摘　　要：从透岩浆流体成矿理论的角度对矿田构造进行了重新认识,提出矿田构造系统是一种复杂性动力系统的观点。根据这个模型,矿田构造是近场应力场与远场应力场强烈相互作用的产物。近场应力场由岩浆成矿系统而不是远场应力场派生,因而不能由矿田构造反演区域构造,但可以从区域构造限定矿田构造。矿田构造常有岩脉和热液脉充填,因而是可识别的。利用构造统计学方法,可以根据岩脉和/或热液脉的分布密度图(或等值线图)预测找矿靶区。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.
