| 摘要: |
| 本文以黄河边上现代不对称波痕的形成为例,结合民和盆地下白垩统第8岩组沉积环境进行类比分析,一改过去传统的"浅水"认识,而把它定为三角洲平原相沉积。因而不对称波痕不能作为某一种沉积环境,它可以广泛生成于不同的环境。因此应更多强调综合分析、类比分析、层序基本单元和体系域分析,使盆地岩石地层单位的古环境解释建立在可靠的理性基础上。 |

| Abstract: |
| The comparative analysis has been made on the modern asymmetric ripple marks along the Huanghe River exemplified by the eighth rock formation of the Lower Cretaceous strata in the Minhe Basin. The formation here are interpreted as the deltaic plain deposits rather than the shallow-water deposits. Therefore the asymmetric ripple marks are not considered as the products deposited in a specific sedimentary environment,but widespread in various sedimentary environments. More attention should be drawn on the synthetic analysis, comparative analysis, element analysis and systems tract analysis so that the palaeoenvironmental interpretation of the lithostratigraphic units in sedimentary basins may be viable. |
