摘要: 本文对该区上二迭—下、中三迭统碳酸盐岩地层的沉积相和牙形刺进行了研究,重点研究了牙形刺的属种和组合,在野外及室内岩石薄片鉴定的基础上,对各组、段的碳酸盐岩相进行了初步划分,从而阐述了牙形动物受沉积环境和岩性控制的关系。本文还讨论了该区牙形刺颜色变化对油气勘探的意义。

Abstract: The depositional facies and conodonts in the Upper permian and Middle-Lower Triassic Carbonatite in this area are studied in this paper. The emphasis is laid on the genera, species and assemblage of conodonts, and a preliminary division is made of the carbonate facies in different formations. Therefore,the relationship between conodont animals and depositional environments and lithology is described. Besides, the colour alteration of conodonts and its significance in exploring oil and gas is also discussed.
