| 摘 要： | 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。

| Abstract: | Triassic system of Tulufan-Hami Basin includ five formations:Jiuchaiguan Formation Shaofanggou Formation Kelamayi Formation Huasangou For-mation and Haojiagou Formation. THe Study of Palynostratigraphy in Tuufan-Hami Basin,four sporopollen assemblege zones are buld: Limatulasporites-Taeniaesporites-assemblege zone. Ara-trisporites-Punctatisporites assemblege zone Punctatisporites-calamospor assemblege zoneand Cycadopites-Lophotriletes-Protoconiferus assemblege zone. Up the evolution ofsporopollen, The paleoclimate is and thermomer at early triassic Period, Late triassic Peri-od Paleoclimate is damp and hot. |
