摘要
通过对澄合矿区古生物、岩性和地球化学等特征的综合分析,认为该区煤系地层太原组为一套海陆交互沉积,以过渡相为主,夹浅海相;山西组为一套近海型的陆相沉积,其中河流相、沼泽相及湖泊相有规律地交替出现。
Comprehensively analyzed paleontological,lithological and geochemical features in Chenghe mining area,considered that the area's coal measures Taiyuan Formation is a set of terrestrial-marine alternating strata,mainly transitional facies,intercalated with shallow-sea facies;Shanxi Formation is a set of paralic continental deposit,of which,fluvial,swamp and lacustrine facies alternatively presented regularly.
