| 摘 要： | 塔里木盆地寒武－奥陶系为海相地层，以碳酸盐岩为主，部分为陆源碎屑岩和浊积岩。含有丰富的生物化石。不同地区的古生物组合不同，反映了沉积环境和沉积条件的差异。可分成１６个生物组合类型，６个生物相区。这为恢复寒武－奥陶纪沉积环境，寻找有利的生储油地带提供了重要标志。

| Abstract: | Cambrian-Ordovician beds in Tarim basin are marine ones dominatedbvcarbonatite, and with part of terrigenous clastic rocks and turbidites containing plenty oforganism fossils. Varing palaeontological assemblage of different areas showed the differ-ence in sedimentary environment and condition. They can be divided into l6 palaeonto-logical assemblage types and 6 biofacies zones,provding the important reference for re-sumption of Cambrian-Ordovician sedimentary environment and seeking for profitablesource sequences and reservoir rocks. |
