【摘要】 北天山山前地带是构造运动十分强烈的地区,褶皱断裂等构造现象十分发育,这里曾发生过多次中强破坏性地震。由于受区域构造长期作用的影响,在北天山山前地区逐步发育形成了多排褶皱背斜及活动断裂,且运动方式具有独特性。该区域作为推覆逆冲的典型地区,其研究成果具有代表性和普遍性。更多还原

【Abstract】 The tectonic motion is very intense in front belt of north Tianshan mountain,drape fault and so on very develop,and there occurred many times destruct earthquakes.Under the effect of regional tectonics,there develop many raws drape anticline and active fault in the front of mountain,and they have especial motion fashion.The region is typical overriding obduction region,and the reseach results have representative and catholicness.更多还原
