摘要
断裂造山带是大陆构造中的一种重要类型。本文通过几个不同时代断裂造山带实例,总结了断裂造山带基本特征:受断裂控制的狭长构造活动带;以成熟度低的陆源碎屑岩和双模式火山岩为特色;热动力变质作用强烈;多期次多类型的构造迭加;横向不均一性突出。笔者按“开”、“合”观点,将断裂造山带划分为四个阶段:地幔隆起;盆地形成;褶皱造山;剪切推覆。四个阶段组合成一个完整的断裂造山旋回。不同时代断裂造山旋回的对比,反映了大陆地壳演化总体进程。
Fault orogenic belt is an important type of the continental tectonics.The
tial features of the fault orogenic belt are summarized from several examples of the fault orogenic belts with different ages-the long and narrow zone controlled by fault,the distinctive terrigenous clastic rocks with low maturity and bimodal volcanic association, strong thermodynamic metamorphism, superposition of multi-phasic and various structures, and prominent transverse inhomogeneity. In the light of the 'opening-closing' stand point,fault orogenic belt can be divided into four stages: mantle uplift,basin formation,fold orogenesis and shear napping. The four stages constitute a complete fault orogenic cycle.The comparison of the fault orogenic cycles with different ages reflects the overall process of the continental crustal evolution.
