摘要
滇中地区存在着众多的褐煤盆地，可保盆地是其中一个小型断陷盆地，新第三纪含煤地层主要由冲积扇—湖泊、沼泽成因层序构成。详细的成因地层分析，厘定出三类等时性地层界面和８个成因地层单位。文中揭示了盆地成因地层格架的演化与聚煤作用的关系。
Among many coal basins in the central part of Yunnan,the Kebao basin is a small scalefault basin.The coal bearing strata are made up of alluvial funlacustrine swamp genetic sequences.On the basic of the genetic stratigraphic analyses,threetypes of the chronostratigraphic interface andeight orders of the genetic stratigraphic are defined.This paper reveals inherent relations with regardto genetic stratigraphic evolution and coal formation.
