摘要
关于元谋层和泥河湾层的划分与对比意见,主张元谋层二分,下部为沙沟组,属上新世;上部为元谋组,属第四纪。泥河湾层三分,下部为稻地组,属上新世;中部为泥河湾组,属下更新统;上部为小渡口组,属中更新统。沙沟组上部与稻地组对比,泥河湾组和元谋组对比。元谋层并不完全等于泥河湾层。
This article tells how to divide and compare the yuan-meng bed and the Ni-he-wan bed. It holds that the yuan-meng bed should be divided into two parts and the Ni-he-wan should be divided into three parts. Therefore the yuan-meng bed does not equal the Ni-he wan bed.
