吐鲁番一哈密盆地三口钻井的地层划分及其生物群特征

The Stratigraphic Division of Three Boring Wellesin Tulufan-Hami Basin and the Features of Fossil Assemblages

以吐鲁番—哈密盆地３口钻井中所获得的生物化石为依据，对其进行了较为细致的地层划分，并讨论了它们的时代归属。根据丰富的胞粉化石，首次确定了三叠纪地层在哈密盆地的存在。

Based on the features of fossil assemblages in three boring wells of Tulufan-Hami basin,the strata of the three boring wells are finely by divided,and their ages also discussed. According toabundant sporo-pollen fossils,the Triassic stratigraphic existence is for the first time affirmed in Ha-mi basin.
