TECTONIC DYNAMICS OF FLUIDS AND ITS ADVANCE

Fluids are important participators and organizers of tectonic processes,such as plate movement,orogenesis,and folding and fracturing of rocks,in geological history and now.It is a time to set up a corresponding subject—“tectonic dynamics of fluids” to improve the study on tectonics of fluids. 　　Tectonic dynamics is a new interdisciplinary frontier between fluid geology and structural geology.It mainly focuses on structures and tectonic dynamics induced by fluid motion,physical conditions (such as temperature and pressure) and their variation of fluids,and interaction between chemical component of fluids and wall rocks in the crust.It takes features of deformation and metamorphism,which formed during interaction between fluids and rocks and have been preserved in rocks,as basic research objects.After studying types,orders,distributions and fabrics of these features,and analyzing and testing physical and chemical information from these features by some techniques,it is intended to reconstruct moving process of fluids,dynamics of interaction between fluids and rocks,and dynamics of mineralization.The research actualities,such as relationship between fluids and tectonics,tectonic pattern of fluids,and fluidogenous tectonics,have been reviewed,and some advances have been introduced and discussed here.
