吐哈盆地三叠系划分为韭菜园组、烧房沟组、克拉玛依组和黄山街组，通过对三叠纪地层的孢粉分析，建立了该盆地的四个孢粉组合带，Limatulasporites—Tae－niaesporites—Alisporites组合带、Aratrisporites—Punctatisporties组合带、Punc－tatisporites—Calamospora组合带和Cycadopites—Lophotriletes—Protoconiferus组合带。依据孢粉的演化得出吐哈盆地三叠纪的古气候为早期的干旱温暖到晚期的潮湿炎热。
The Triassic in the Turpan-Hami basin are divided into the Leukagen Group, the Tanfanggou Formation, the Karamay Formation and the Huangshanjie Formation. Based on the sporopollen analysis of the Triassic strata, four sporopollen assemblages, Limatulasporites-Tae -niaesporites-Alisporites, Aratrisporites-Punctatisporties, Punc-tatisporites-Calamospora, and Cycadopites-Lophotriletes-Protoconiferus. According to the evolution of sporopollen, the Triassic paleoclimate in the Turpan-Hami basin was humid and warm in early to late drought period.
