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。
Taking the formation of modern asymmetrical ripples on the Yellow River as an example, this paper analyzes the analogy of the sedimentary environment of the Cretaceous No.8 lithofacies in the Minhe Basin, aiming to change the traditional “shallow water” Plains facies deposition. Therefore asymmetrical marks can not be used as a sedimentary environment, it can be widely generated in different environments. Therefore, more emphasis should be given to comprehensive analysis, analogy analysis, basic unit of sequence and system analysis, so that the paleoenvironmental interpretation of the lithospheric units in the basin is based on a sound rationality.
