摘要
以碳酸盐台地内部、边缘及盆地３个不同相区的岩石地层基本单位———组为实例，从层序地层学角度论述了岩石地层单位界线的厘定与优化方案，认为以层序（尤其是Ⅰ型层序）界面及体系域之间界面（即初始海泛面、最大海泛面等）作为一些组的新界线，将会更有利于野外岩石地层单位的识别与对比。
With the examples of the three formations in different facies areas, including the platform interior, the rim ramp and the shelf basin , the author discusses the revision and modification of the lithostratigraphic units′ boundaries from the angle of sequence stratigraphy. It is suggested that if the sequence boundary(SB), esp. the Type I, and the boundaries between the depositional system tracts(i.e. FFS or TS, and mfs )could be adopted as the boundaries of some lithostratigraphic units, i.e. formation, it would be much more helpful to identify and correlate the lithostratigraphic units in the field work.
