Structural geology is the most comprehensive branch of earth science, and its research scope includes rock deformation (also called structural geology in a narrow sense) and geotectonics. The main research contents are: geometry, kinematics, dynamics, tectonic chronology and applied tectonic geology.
In recent 30 years, structural geology has made great progress in the study of rock deformation process and mechanism (elastic and plastic, brittle and ductile deformation), ancient strain and ancient stress, tectonic system and so on. Soft sediments, synsedimentary structural deformation and salt structures have also received great attention. However, the research progress of tectonic chronology is not ideal, and the data are gradually accumulated, which has become the frontier field of structural geology research. In China, compared with theoretical structural geology, the progress of applied structural geology is more prominent, such as the prediction of deep position of structural mineralization, the discovery and exploration of fractured oil and gas reservoirs and so on.
The study of lithospheric plate structure is also deepening. The compilation of the third generation magnetic stripe map of the ocean floor gives people a brand-new understanding of the six stages of the evolution of the ocean floor structure since the Middle Jurassic, and finds that the plate boundary properties (subduction zone, expansion zone and transform fault) can be constantly changed. It is gradually realized that the typical structure in the deep part of the continental collision zone is a kind of thrust structure (some people call it crocodile structure), and the formation period of the continental collision zone is not the main metallogenic period. The formation, reconstruction and restoration of ancient landmasses and plates are progressing steadily, and the systematic study of intraplate deformation has made remarkable achievements in China, North America and Western Europe. The complex process of meso-Cenozoic intraplate deformation (5-6 times deformation) is gradually recognized. The interaction between lithosphere and other lithospheres has gradually attracted more and more scholars' attention.
