摘 要: 为验证粒度分析是否适用于颗粒灰岩,选取山东济宁张夏组一层亮晶砂屑灰岩为目的层,详细研究目的层及其上、下岩层的野外及镜下特征。研究发现:目的层发育明显的交错层理,分选性、磨圆度极好,且为亮晶胶结,将其定为潮下高能颗粒滩相沉积,这与根据粒度分析得出的颗粒滩相沉积一致。因此,粒度分析可以应用于颗粒灰岩的研究。
关 键 词: 沉积学;粒度分析;沉积环境;砂屑灰岩;颗粒滩相

Abstract: In order to test whether particle size analysis could be used in the study of grainstone, this paper studies the field and microscopic characteristics of one sparry calcarenite layer in Shandong Jining Zhangxia group, as well as its upper and lower strata. We find that the target strata has a good sorting and psephicity with cross-bedding and sparry cementation. We regard its depositional environment as high-energy grain shoal in subtidal, which is consistent with the result of grain shoal based on particle size analysis. Therefore, the particle size analysis could be applied to the study of grainstone.
Key words: sedimentology; particle size analysis; depositonal environment; calcarenite; grain shoal facies
