摘要
对板块说应持分析态度,既充分肯定它的创见,又要看到其不足。张文佑倡导的断块说强调地质演化中的陆洋地壳转化,即拉张造洋、挤压造陆。近年来提出的开合说,继承了板块说、断块说和新地槽-地台说的合理内核。笔者认为,断块-开合大地构造说是中国大地构造研究中有代表性的思潮。本文概括了其基本观点,强调了开合中的多模式、多旋回和非封闭性、不可逆性。
In the appraisal of the plate tectonic theory,one should not only fully affirm its creative idea,but also point out its shortcomings.The theory of fault-block tectonics proposed by Zhang Wenyou em-phasizes the transformation of continental and oceanic crust in the geologic evolution,i.e.,thalattogenesis caused by extension and epeirogenesis by compression.The theory on opening-closing tectonics developed recently inherits the reasonable concepts of plate tectonics,fault-block tectonics and new geosyncline-plat-form tectonics.The author thinks that the fault-block and opening-closing tectonic theory is a representa-tive trend of thought in China's tectonic study.The paper discusses the basic view of this theory and em-phasizes the multi-model and polycyclic processes and nonclosed nature and irreversibility in opening-clos-ing processes.
