摘　　要：流体是地球的重要物质组成,其构造作用与动力学是地质力学与构造学重要的研究方向。流体构造动力学是介于流体地质学、地质力学和构造地质学之间的一个交叉学科。文章介绍了流体构造动力学的概念、主要研究内容、流体的构造作用方式及构造类型与特征,总结了近年来在流体构造动力学与成矿研究过程中取得的一系列重要进展。主要有提出液压致裂的新动力学机制、发现斑晶堆积构造并指出斑岩是岩浆房中部分结晶残余岩浆再侵位的产物及发现并厘定构造混积岩等多个方面,总结了存在的问题并指出了进一步研究的方向;指出流体作为构造作用的主要参与者和重要组织者,不仅对成矿流体的运移通道及其沉淀与就位的空间进行开拓,更重要的是作为载体运移、富集成矿元素并为最终成矿奠定基础。Fluid is an important constitute of the earth,and tectonics and dynamics of fluids are major research branches of geomechanics and tectonics.Tectonic dynamics of fluids is a new interdisplinary subject among fluid geology,geomechanics and structural geology.This contribution introduces the concept and the framework of the subject of tectonic dynamics of fluids.In addition,it summarizes a series of important advances in the study of tectonic dynamics of fluids and metallogenesis in recent years,including coming up with the new mechanics for fracture caused by hydraulic pressure,discovering the porphyry accumulation structure,indicating porphyry as the product of reemplacement of some crystallized residual magma in magma chamber,discovering and determining tectonic peperite,and so on.Moreover,some new research advances are also presented here.Finally,some key scientific questions are pointed out.It is concluded that fluids not only create fractures and spaces for ore-forming fluids to be transported and to precipitate but also transport and enrich ore-forming elements,thus laying a foundation for the final formation of ore deposits.
