| 摘 要： | 志留系在博罗科努山地区分布比较广泛,且厚度巨大,岩性、岩相稳定。但对其内部划分,尤其是中、上部,缺乏标准化石作为依据。1988年笔者在原划归上统的库茹尔组中,首次采到角石Sichuanoceras sp., Parahelenites cf. rarus和三叶虫Encrinurus sp.等化石。因而库茹尔组很可能属志留系中统,而非上统。

| Abstract: | The Silurian is widely distributed,complete in strata,large in thickness,and steady in lithology and lithofacies in the Bolhinur Mt. region. However the lack of index fossils led to the difficulties in the classification of the Silurian,especially its middle and upper parts. According to the newly discovered cephalopoda and trilobita in 1988,identified as Sichanoceras sp. ,Parahelenites cf.rarus and Encrinurus sp. .Kuruer Formation, which was assigned to be of early Late Silurian,is now evidenced to be of middle to late Middle Silu -rian. |
