摘要
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 stratal records are not continous in the sedimentary basin due to theunconformities, the patterns of which in time and space may reveal the origins. Theanalysis of unconformity origin in the sedimentary basin includes studying erosion(subaerial and submarine erosion) and non-erosion as well as analysing their controls,suchas continental elavation,spa level changes and tectonic roovements, In this paper, the briefintroduction on unconformity origins and analysis methods is taken, after the historyreview of the study of the unconformity.
