摘要
通过对元谋组进一步研究,同时综合地层、古生物化石、磁性地层、元谋人牙齿化石及新构造运动等方面材料,对元谋组时代进行了探讨,证明元谋组时代为早更新世。 元谋人化石产于元谋组的第四段25层中。地层层次清晰,没有紊乱,磁性地层重新研究得出第四段的磁极性相当松山反向期中的奥都维事件附近,元谋人的年代仍为距今170万年左右,而不是刘东生等认为的50—60万年。
According to the further study of Yuanmou formation and the comprehensive survey of Lithostratigraphy, paleontological stratigraphy, magnetic stratigraphy, the new tectonic movement of Yuanmlou basin and the morphology of human teeth, the age of Yuanmou formation is proved to be early Pleistocene in this discussion.
The locality of 'Yuanmou Man' lies at the 25th layer of the fourth member of Yulanmou formation. A further investigation of the strata indicated that the sequence of strata is very clear without disorder. The mew study on magnetic strata proved that magnetic polarity column of the fourth member of Yuanmou formation is situated near the Olduvai at the Matuyama reversed polarity epoch, and the age of 'Yuianmou Man' is still 1.70m.y. B.P., rather than 0.50-0.60 m.y. B.P. as considered by Liu Tungsheng et al..
