摘要
层序地层学的理论思想被认为是地层学和沉积学中最伟大的革命。从九十年代以来，其概念体系已日臻完善并在全球范围内得到广泛使用。本文根据作者在新一轮１∶５万区域地质调查工作中的体会和经验，对层序地层学的研究方法作一简要介绍。其内容包括：层序地层学的理论基础，野外和室内的基本工作方法，层序地层单位与其它地层单位的关系。
Since the 1990's, the concept system of sequence stratigraphy has been perfected increasingly, and applied world widely. At present, its research field has already covered the marine and terrestrial oil gas bearing basins with various tectonic and paleogeographic background, the sedimentary stratabound deposits, the new round regional geological surveying, and the perfection of chronostratigraphic network. The sequence stratigraphy now is considered as the most important and hopeful way for study of the global rhyme and event occurring in sedimentary strata, and the great revolution in the field of stratigraphy and sedimentology. On the basis of our experience in the new round 1∶50000 regional geological surveying, this paper generally introduces the theoretic basis of sequence stratigraphy, its working methods (including both the fieldwork and indoor work), the relations of sequence stratigraphic unit with that of other stratigraphies, such as the lithostratigraphy,biostratigraphy, and chronostratigraphy etc., and the points for attention in the sequence stratigraphic works.
