摘要
笔者通过对华北地台北缘色洛河群中所觅得的化石、同位素地质年龄及与邻区对比等综合研究,认为色洛河群的形成时代置于早古生代寒武纪为宜。
On the basis of comprehensive study of the fossils collected from the Seluohe Group, the isotopic age and comparison of the Seluohe Group with that of the adjacent areas, on the northern margin of the north China platform, the Seluohe Group should be referred to the early Plaleozoic Cambrian period.
