摘要(Abstract)：
根据二连盆地阿拉坦合力凹陷内坦参1井钻及的以红色砂泥岩为主的地层及其中分析出来的孢粉化石建立了伊和高勒组、吉尔嘎郎图组、代喇嘛庙组和沙木尔吉组4个新的岩石地层单位,根据前三个组中所包含的3个孢粉组合(从上到下为:Osmundacidites-Aratrisporites-Apiculatisporis-Cycadopites组合、Li matulasporites-Annu-lispora-Monosulcites组合和Li matulasporites-Lundbladispora-Florinites组合)可以确定伊和高勒组和吉尔嘎郎图组的时代为中三叠世,代喇嘛庙组的时代为早三叠世,二连盆地的三叠系可以和新疆、陕西、江苏及河南等地的相应地层较好地进行对比。
