摘要
1989～1990年间在湖北省郧县发掘出远古人类的颅骨化石,命名为“郧县人”。本文对含化石地层的地质剖面(厚18m)进行了磁性地层学和古环境的研究工作,共采集78个样品,测试了样品的剩余磁化强度、磁化率及磁化率各向异性参量。通过对测试结果的分析,初步确定“郧县人”化石地层的年代约为0.83～0.87Ma.“郧县人”生活在一个冷转暖的古气候环境。
Two skull fossils of homo,which was called 'Yunxian homo',were found in Yunxian of Hubei during 1989-1990. This paper presents results of magnetic stratigraphy and pa-leoenvironment of the section with the fossil bed. RM (remanent magnetization)、X(magnetic susceptibility);and AMS (anisotropy of magnetic susceptibility) of 78 specimens in the section were measured. It was determined that the age of the fossil bed of Yunxian homo is 0. 83 ~ 0. 87Ma and the homo lived in the paleoclimatic environment transformed from cold to warm.
