| 摘 要： | 大青山逆冲推覆体系是三叠纪中后期至白垩纪漫长的脉动式的造山过程形成的一套完整的逆冲推覆体系，是由一系列由南向北逆冲推覆构造岩片相互叠置构成。它涉及了前寒武纪变质杂岩，古生代沉积地层和中生代陆相沉积地层，并伴随有印支期岩浆活动。在变形旋回上表现为多期和多阶段的脉动式，印支期表现为南向北逆冲推覆和强烈的岩浆活动，燕山期表现为南南东向北北西推覆，形成了褶皱系统和劈理系统。

| Abstract: | Daqingshan thrust system is a suit of integrated the thrust system which was formed during far long arteries orogeny,thrusting from south to north. It involved Precambrian metamorphic complex, Plaeozoic sedimentary stratum and Mesozoic sedimentary, and concomi-tancy Indo - China magma activity. Thrusting deformation represented multepisodes and mult-stages arteries deformation. Indo - China epoch deformation represented thrusting from south to north and strong magma activity. Yanshan epoch deformation represented thrusting from southeast to northwest, formed folds system and cleavage system. |
