Progresses and problems in the study of the rheological structure of the continental lithosphere

WEI Rong-qiang,ZANG Shao-xian(School of the earth and space sciences,Peking University,Beijing 100081,China)  
A great deal progress has been made in the study of the rheological structure of the continental lithosphere since 1960's,not only in theory but also in the application.With such great progress it has become known that the lithosphere is the rheological body other than the rigid or the elastic one.Based on the experiments on the rocks or the minerals in the lithosphere,the concept of rheological stratification and the 1-D rheological model for the lithosphere are constructed,with which some tectonics are explained successfully.Furthermore,3-D rheological structure of the lithosphere are studied in recent years,from which it can be seen that the rheological structure is layered in the vertical direction,but the thickness and the depth of each layer varies horizontally.Based on the 3-D rheological structure of the lithosphere,people have begun the geodynamic study in 3-D space,other than the simple usage of the rheological strength envelopes in the kinematics model and dynamic model.However,more and more new problems appear at the same time because of the development of the rheology of the lithosphere and the complexity of the lithosphere.
