摘要
20世纪60—70年代,是我国大地构造研究领域学术思想最为活跃的时期,1979年全国第二届构造地质学术会上,出现八大学派的领军人物同台亮相阐明各自观点的壮观场面。尔后多旋回学说的领军人黄汲清及其继承人之一姜春发、断块构造学说的领军人张文佑及其继承人之一张抗、区域大地构造学说的领军人马杏垣及其继承人之一杨巍然几乎同时分别提出多旋回手风琴式开合、断块开合和"开""合"构造观点。三大学派殊途同归携手创建了具有中国特色的开合构造理论,开合构造理论是研究开合运动及其形成的地质体的结构构造特征和规律的学科。本文是对开合构造研究的新一轮成果的总结。(1)开合运动的基本属性为:开合运动是一切地质体运动的基本形式;它揭示了各种地质运动之间的内在联系和本质特征;开与合是地球动力学中一对主要矛盾,二者相互依存、相互对立、相互转换,转换点(区)时空的定位具有重要的理论和实践意义。(2)地学开合律为开合运动规律的总结:它包括开合运动规模上的级次性和层次性;时间上的旋回性、空间上的互补性、演化上的方向性,并总结出由简至繁和从点开始、到线、再到面的开合迁移演化模式。(3)开合构造研究中几个重要概念:开合标志是指能确定开合属性的各种地质现象,它是研究开合构造的基础资料;开合建造及建造序列是研究开合过程中物质的组合特征,它们反映了该物质组合形成时的构造环境及开合构造演化的阶段;开合构造类型是根据开合标志的综合,总结出不同级次和层次的开合运动的组合规律,它反映了大陆-大洋开合演化的不同阶段,目前已总结出8种开合构造类型;开合构造单位是开合构造综合特征和开合构造类型空间分布规律的总结,提出了以大陆一级构造单位为开合构造集群的新概念,它强调集群内各
The 60-70 sin the 20 th century,was the most active period in academic thinking within Chinese geotectonics circle.In the year 1979 at The 2nd All-China Conference on Structural Geology a memorable scene appeared that the leading lights of the 8tectonic schools in China showed up at the same stage to illustrate their own points of view.After that,the leading light of the theory of polycyclic tectonics,academician Huang Jiqing and one of his successors Jiang Chunfa,the leading light of the theory of fault block tectonics,academician Zhang Wenyou and one of his successors Zhang Kang,the leading light of the theory of regional geotectonics,academician Ma Xingyuan,and one of his successors Yang Weiran,proposed respectively at about the same time the polycyclic accordion shaped openingclosing tectonics,the fault-block openingclosing tectonics and the＂opening＂＂closing＂tectonics.The 3tectonic schools reached at the same goal by different routes and made a concerted effort to construct the openingclosing tectonic theory with Chinese characteristics.The openingclosing tectonics deals with the openingclosing movement and the textural structural features and regularities of the geological bodies formed.The present paper is a summary on the fresh round research results of the openingclosing tectonics.（1）The fundamental attribute of the openingclosing tectonics is that openingclosing movement is the major form of the movements of all geological bodies.It reveals the internal relation and intrinsic characteristics of various geological movements.Opening and closing are a pair of elemental contradictions in geodynamics.Both of them are mutual dependent and antagonistic,and are transformable,and the positioning of the time and space of the turning point（zone）of the transformation is both of theoretical and practical significance.（2）The openingclosing rule in geosciences is a summary on the regularities of openingclosing movement including the ranks and layering in various scales of openingclosing tectonics,th
