| 摘 要： | 针对陆相地层发育特点,讨论了层序地层学基本原理在陆相地层中应用的可行性。指出陆相层序发育晚期常出现强制性湖退,从而在湖平面由相对稳定的高水位下降到相对稳定的低水位这段时间内,形成了大型前积地层楔;该强制性地层楔的底界面为整合下超面,顶界面为区域性侵蚀界面。此时不宜按照传统层序地层学的观点将该地层楔的底界面作为层序界面,层序界面划分在该地层楔的顶界面更符合经典层序地层学的理论真谛;强制性湖退地层楔应为陆相三级层序单元内高水位体系域之上的“新”体系域,陆相层序地层三级层序单元应该四分;陆相层序地层四分方案的单元是可识别的,且具有理论意义和实际应用价值。

| Abstract: | The author aimed at the character of the continental stratum development to discuss the feasibility of the application of classical sequence stratigraphy to continental stratum .We point out that the compulsory lake regresson often appears in later period of continental stratum development ,so large progradational stratum wedge come into being when lake level fall from the high relatively stable water level to the low water level, the bottom interface of this compulsory stratum wedge is conformable down lapping surface, it's top-interface is regional erosional boundary ,in this circumstance ,it is not feasible to take the bottom interface as sequence boundary ,and the top interface as sequence boundary is more correspond to the theory of classic sequence stratigraphy. Compulsory regressive stratum should be a new system tract on high level system tract in continental third grade sequence element ,continental sequence stratigraphy third grade element should be classified to four parts ;the element of the scheme of four division can not only be distinguished,but also has significance in theory and in practice. |
