通过对山东巨野煤田煤系地层之岩性、沉积构造、古生物特征、测井曲线、微量元素及粒度概率曲线等资料的综合分析，认为该煤田早二叠世时处于以河控作用为主，兼受潮汐作用影响的浅水三角洲环境。沉积环境经历了水下三角洲平原、边缘三角洲潮汐平原、边缘三角洲沼泽平原、下三角洲平原、上三角洲平原五个沉积阶段，总体构成了一个进积序列，反映了由浅海相→过渡相→陆相的沉积演化过程。 Based on the comprehensive analysis of lithology, sedimentary structure, paleontology, logging curves, trace elements and probability curves of grain size of coal strata in Juye coalfield of Shandong Province, it is considered that the river was dominated by river control during the Early Permian , As well as the shallow delta environment affected by tides. The sedimentary environment has undergone five sedimentary stages including underwater delta plain, marginal delta tidal plain, marginal delta swamp plain, lower delta plain and upper delta plain, which generally constitute a sequence of progradation, reflecting the transition from shallow marine facies to transitional facies to continental facies Sedimentary evolution.
