| 摘 要： | 从全球尺度对原大西洋与古亚洲洋构造域大地构造旋回及其演化特征进行对比研究,有助于了解巨型构造域内的区域构造演化的关联性。建立古大陆构造单元属性"动态行为"的理念,将复合造山区与毗邻大地构造单元进行关联分析,揭示出华北前陆盆地的形成发展与毗邻复合造山区的构造演化进程密切相关。华北及其以北地区晚古生代—早中生代构造格架的主体特点是:1)蒙古—兴安复合造山区发育石炭纪—二叠纪陆表海盆地、裂陷槽和上叠盆地,及三叠纪的山间盆地;2)华北前陆盆地与复合造山区构造演化进程同步,在古陆上形成石炭纪海相和海陆交互相沉积,二叠纪—中三叠世的陆相沉积,以发育红层和局部形成膏盐为特点;3)原华北古陆北缘"构造岩浆活化带"属晚古生代—早中生代蒙古—兴安复合造山区最南端的构造单元,具有构造前锋带属性。

| Abstract: | A comparative study of geotectonic cycles and evolution characteristics of the tectonic domain from the Atlantic Ocean to Paleo-Asia Ocean on the global scale is beneficial to understanding the regional tectonic evolution of the giant tectonic domain.The establishment of the concept of dynamic behaviors of the attributes of paleocontinents tectonic units and the correlation analysis of the composite orogenic area and its neighboring tectonic units have revealed that the formation and development of the Nort... |
