Studying environgeological records of continental basins includes commonly methods such as formation, development and evolution of basins, geochemistry and paleoclimate of sediment forming,compaction and catagenesis after sediment accumulated. In addition to inorganic matter, the variation of chemical component and texture of organic matter heated in compaction and diagenetic change is also a part of environgelolgical records in basins. The object of environgeological research is to appraise the formation and latent energy of fossil fuel. The writers promulgated the difference of three basins in fossil fuel formation and potential power except for the resemblance in formation and envolution of basins,sedimentary geochemisty,paleoclimate,diagensis and hydrocarbon generated by studying environgeological
records of three Cenozoic fault basins in Longchuan, Ruili and Baoshan in western Yunnan. The paper also indicates that the coal gas and oil of early maturity (low maturity)is fit for exploring in Longchuan basin and biogenic and coal types of gas of near-surface in Baoshan. But the potential energy of fossil fuel is not good and probably there is few shallow biogenic gas only in Ruili basin.
Key words: Cenozoic Era; Fault basin; Environgeological record; Fossil fuel; Yunnan province.
