摘　　要：为阐明塔里木盆地昆仑山前古近系沉积特征,以野外实测剖面为基础,结合井下资料分析表明,昆仑山前古近系自下而上可分为阿尔塔什组、齐姆根组、卡拉塔尔组、乌拉跟组及巴什布拉克组。古近系发生两次海侵-海退,每个组(段)发育有典型而相对单一的沉积相类型,自下而上发育海湾(阿尔塔什组)-潮坪(齐姆根)-碳酸盐岩台地(卡拉塔尔组)-潮坪(乌拉组)。In order to expounding the Sedimentary facies in Paleogene of Kunlun piedmont zone,Tarim Basin,based on fine outcrop description and log information,the results show that the Paleogene strata of Kunlun piedmont zone can be divided into five formations from bottom to top： Artashi Formation,Qimugen Formation,Kalataer Formation,Wulagen Formation and Bashibulake Formation.The transgression and regression happened twice in Paleogene system,and each formation or section developed typical and relatively single sedimentary facies.The strata of Paleogene system developed gulf-tidal-flat-carbonate platform-tidal flat facies from bottom to top.
