摘　　要：阿腊德依克赛组是北疆北准噶尔地层分区玛依力山地层小区晚石炭世最顶部一个组级岩石地层单位,出露于乌尔禾北东的哈拉阿拉特山一带。新近地质调查证实,阿腊德依克赛组并非前人所述的南倾单斜层,粒序层理、层理、层面等构造证实本组总体为一北倾的正常层序,时代为晚石炭世卡西莫夫期。Aladeyikesai Formation,belonging to Mayili Mountains stratomicroregion of North Junggar stratosubregion, which located in Hala＇ alate Mountain,West Junggar, is the most top lithostratigraphic unit in Late Carboniferous.Based on the new data and progresses gained in recent studies,Aladeyikesai Formation is a dipping-north rather than the dip- ping-south monocline by the researchers＇ reported, it confirmed by graded bedding,stratification and bedding plane. Moreover, its geological age is the Late Carboniferous Kasimovian.This study provided the latest information to ex- pound clearly the most basic geological characteristics of Aladeyikesai Formation,such as occurrence form,distribution, stratigraphic sequence,geological age and so on.Meanwhile,we update the lithostratigraphic unit information of Aladeyikesai Formation.
