摘要
中国西北、渤海湾、鄂、豫、苏、皖及南方地区的含油气盆地均发现有第三系哺乳动物化石,根据动物群性质及其与共生微体化石的关系,并根据古地磁、同位素绝对年龄、颗石藻等浮游生物化石确立了与欧美第三系标准层序的对比关系,证实哺乳动物化石在油气区地层对比乃至研究古气候、古环境等方面都能起到应有的作用。目前,胜利、辽河、江苏等油田井下第三纪地层中也发现了哺乳动物牙齿化石,有利于解决地面与井下以及各油气区之间的对比。
The present paper deals with some mamal fossils discovered in hydrocarbon-bearing basins in China and the property of the biota, their ages and their correlation both at homeand abroad. The relation between the biota and its associated microfossils is discussed. Theauthors conclude that both of them indicate basically the same age. It is confirmed thatmammal fossil is promising in geologic correlation, palaeoclimate, and palaeoenvironmentstudies. Up to now, mammal tooth fossils have been found in the wells in Shengli, Liaohe andJiangsu Oil Fields. Therefore, a collection and study of the mamal fossils in exploratedhydrocarbon bearing basins in the future should be emphasized.
