摘要
Abstract
Based on the field geological investigation and drilling core,detailedly observes on the characters of the lithology,biological fossils and sedimentary structures of the upper Permian Longtan Formation in Moxinpo exploration area,and investigates the depositional environment and coal-accumulating patterns with the theory of sedimentary environment analysis and coal-accumulating laws.The Longtan Formation coal-forming swamp directly developed on tidal flat.The mining coal seam has a little thickness but with a stable stratum,broadly developed,easily compared,which mostly is high-ash and medium-high sulpher in this area.During the late Permian,the Formation experienced 10 times of transgression and 11 times of regression,alternately developing lagoon,tidal flat and platform,mainly are marine-terrigenous facies coal-accumulating buildup,which belong to localized carbonate peat tidal flat-platform coal-accumulating environment.The research result provides the theoretical support to prospecting direction for the exploration of replacement resources in this coal mine.关键词
