In the appraisal of the plate tectonic theory, one should not only fully affirm its creative idea, but also point out its shortcomings. The fault-block tectonics proposed by Zhang Wenyou emphasizes the transformation of continntal crust and oceanic crust in the geologic evolution, i. e. , thalattogenesis caused by extension and epeirogenesis by compression. The opening-closing tectonics developed recently inherited the reasonable viewpoints of the plate tectonics, fault-block tectonics and new geosyncline-platform tectonics, the author thinks that the fault-block and ope-ing-closing tectonics theory is a representative trend of thought in tectonic studies in China. The paper discucsses the basic views of this theory and emphasizes the multi-model and polycyclic processes and nonclosed nature and irreversibility in opening-closing processes.
