自1984年首次提出C-俯冲(中国陆内俯冲———Chinese-Subduction之简称)观点后,引起了国内地学界强烈的反响。经过近20年的发展,这一观点已被越来越多的地质现象证实,也被越来越多的人们所接受。这一观点认为,C-俯冲带在大地构造位置上处于古老褶皱山系与内陆盆地边缘坳陷之间;C-俯冲带早期为正断层,后期转化为逆断层,成为盆地坳陷边缘主动向山系潜滑的俯冲断层;C-俯冲带有着良好的成油条件,在逆冲带形成早期往往发育着较厚海相和海陆过渡相沉积,后期形成前渊盆地,在中、新生代可形成良好的湖相成油环境;青藏高原的崛起除了与新生代印度板块与欧亚板块发生碰撞有关外,还与龙门山C-俯冲活动有关;C-俯冲不仅在中国中西部存在,也存在于中国的东部地区,C-俯冲观点的提出,丰富、完善了板块学说关于中、新生代造山带形成的模式,是中国地学工作者在大陆构造理论上的创新。
The concept of C-subduction (abbreviation of Chinese-Subduction) has been raised for the first time since 1984, which has aroused strong repercussions from domestic scholars. After nearly 20 years of development, this view has been confirmed by more and more geological phenomenon, which is also accepted by more and more people. This view suggests that the C-subduction zone is located between the ancient fold-trending continental margin and the marginal depression of the inland basin at the tectonic setting; the early C-subduction zone is a normal fault and later turns into an inverse fault and becomes the active edge of the basin margin Subducting faults are subducting faults. C-subduction zone has favorable oil-forming conditions. In the early stage of thrust belt formation, thicker marine facies and sea-land transitional facies sediments are often formed. In the later period, foredeep basins are formed, Good lacustrine oil-forming environment; the rise of the Qinghai-Tibet Plateau is related to the C-subduction of the Longmenshan, except for the collision with the Cenozoic Indian Plate and the Eurasian plate; C-subduction not only exists in central and western China but also exists in The introduction of the C-subduction point in eastern China enriched and perfected the theory of plate tectonics about the formation of Meso-Cenozoic orogenic belts, and is a theoretical innovation of geoscientists in China on the mainland.
