摘　　要：构造动力成矿作用是指在成矿过程中以构造动力成矿作用为主导的一种成矿作用。本文阐述了与动力成矿作用有关的基本概念及其差异 ,按成矿构造背景、构造成矿阶段、构造成矿方式提出了构造动力成矿作用三级划分方案 :即一级划分为挤压型、拉张型和剪切型 ;二级划分为建造型和改造型 ;三级划分 ,在建造型中有动力分异作用 ,在改造型中分为动力粘流作用、动力变质作用、动力分异作用和动力热液作用。在此基础上对构造动力成矿作用的基本特征、形成条件、形成机理、研究意义和注意问题进行了初步探讨。Tectono dynamic metallogenesis refers to a metallogenic process in which tectono dynamic metallogenesis plays a leading role. This paper discusses tectono dynamic metallogenesis and the relevant concept and their differences, according to metallotectonic background, tectono metallogenic stage and tectono metallogenic style, proposes the gradation of tectono dynamic metallogenesis.The first grade involves compressive,tensile and shear types. The second grade involves formation and transformation types. The third grade involves dynamic differentiation in the formation type, and dynamic viscous flow,dynamic metamorphism,dynamic differentiation and dynamic hydrothermalism in the transformation type. Based on the above discussion, the author expounds the basic characteristics, forming condition, forming mechanism, research significance, and problems of tectono dynamic metallogenesis.
