摘要	The two sections containing hominoid fossils in the Yuanmou Basin, Yunnan Province have been studied by means of magnetostratigraphy. The results are as follows. The Xiaohe section records over 8 polarity zones corresponding to Cande-Kent95 time scale, including C3Br.1n, C3Br.1r, C3Br.2n, C3Br.2r, C4n.1n, C4n.1r, C4n.2n and C4n.2r, attaching to Late Miocene. This section comprises two layers of hominoid fossils: the lower layer (the 1st layer in fig. 4) which records the lower portion of C4n.2r with paleornagnetic age of 8.20-8.10 Ma and the upper layer (the 16th layer in fig. 4) which records C3Br.1r with paleornagnetic age of 7.20-7.15 Ma. So the age of hominoid fossils in the Xiaohe section is about 8.20-7.15 Ma. The Leilao section records over 11 polarity zones corresponding to Cande-Kent95 time scale, including C3Br, C3Br.1n, C3Br.1r, C3Br.2n, C3Br.2r, C4n.1n, C4n.1r, C4n.2n, C4n.2r, C4n.3n and C4n.3r, attaching to Late Miocene. This section also consists of two layers of hominoid fossils: the lower layer (the 3rd layer in fig. 3) which records C4n.2r with the age of 8.20-8.10 Ma and the upper layer(the 19th layer in fig. 3) which records the middle portion of C3Br with the age of 7.15-7.1 Ma. So the age of hominoid fossils in the Leilao section is about 8.20-7.10 Ma. Sedimentary environments reflected in both sections are extremely similar, and the ages of hominoid fossils are of correspondency. The age of the lower and upper fossil layers is 8.20-8.10 Ma and 7.20-7.10 Ma respectively, which probably imply that hominoids living in Xiaohe and Leilao basins have uniform activity areas. There were hominoids activities all along during 8.00-7.00 MaBP in this field.; The two sections containing hominoid fossils in the Yuanmou Basin, Yunnan Province have been studied by means of magnetostratigraphy.
