叠层石的形态特征既受沉积环境的影响,又受微生物类群所制约。尽管目前对控制叠层石形态特征的主要因素尚存在争议,但是对于叠层石宏观特征受沉积环境影响较大,可指示沉积环境这一观点在学术界已达成共识。目前,针对沉积环境对叠层石宏观形态特征的控制作用尚缺乏系统性的研究。本文通过总结前人研究成果,对控制叠层石宏观形态特征的沉积环境因素进行分析,并将其归纳为水动力强度、水深、水流方向、可容纳空间和沉积物供给五大方面,这一结论对利用叠层石进行古沉积环境分析具有一定意义。
The morphological characteristics of the monolith are influenced not only by the sedimentary environment but also by the microbial groups. Although the main factors that control the morphological characteristics of monoliths are still controversial, there is a consensus in academia that the macroscopic characteristics of monoliths are greatly affected by sedimentary environment and that sedimentary environment can be indicated. At present, there is no systematic research on the controlling effect of sedimentary environment on the macroscopic morphological characteristics of layered rocks. This paper summarizes the sedimentary environmental factors that control the macro-morphological characteristics of strata by summarizing the previous research results and summarizes them into five aspects: hydrodynamic strength, water depth, water flow direction, accommodation space and sediment supply It is of certain significance to analyze the paleo-sedimentary environment by using strata.
