摘　　要：首次提出了剪切带构造成矿系统概念，明确指出它具有整体性、结构性、层次性、开放性、网络性、同源共生性、分带过渡性及最优化结构等特性，而网络性是其最重要特性；重点确定剪切带构造成矿系统特征参数，分析系统结构，提出将系统集约化程度、有序度和自组织性等系统特征参数作为判断其聚矿功能的定量指标，解析成矿系统结构和聚矿功能；阐明了剪切带构造成矿系统研究的具体方法和重要意义。Ore forming system of shear zone tectonics is controlled by ductile brittle shearing,and reformed by many processes such as deformation,metamorphism,fluid function,magmatism,ore forming,and so on.Ore forming materials are activated,transported and accumulated by shearing action,and finally enriched and ore formed.It is not only the self similar system which has multi levels embeded construction,but also an open system far from equilitium which has compact function construction.The concept of ore forming system of shear zone is put forward for the first time. The authors point out definitely that it is entirety, structure,embeded levels,openness,complex network,co existence,zoning continuum and optimum structure(the complex network is most important), emphatically define the parameters of intensity degree,ordering degree and self organization which are quantitative targets of assessing the ore forming capacity of the system, and inquire into the dynamics of the system.The authors expound yet the concrete methods and the theoretical and practical significance of the researches of ore forming system of shear zone.
