沉积盆地的不整合使地层记录是非连续性。不整合的时空型式可以反映出不整合的成国。不整合成因分析不仅是对不整合形成的主要方式——侵蚀（包括陆上暴露侵蚀和水下侵蚀）和非侵蚀作用的研究，而且对其控制因素如大陆抬升、海平面变化以及盆地构造活动等进行分析。本文在对不整合研究进行历史回顾的基础上介绍了近来有关对不整合成因分析的认识和一些分析方法。
The unconformity of the sedimentary basins makes the formation record discontinuous. The non-integrated space-time pattern can reflect the unconformity of the developed countries. The analysis of the causes of unconformity is not only a study of the main modes of unconformity formation, erosion (including land-exposed erosion and underwater erosion) and non-erosion, but also its control factors such as uplift of the mainland, sea-level change and tectonic activity Analysis. Based on the historical review of unconformity research, this article introduces the recent understanding and analysis of the causes of unconformity.
