| Abstract: | Magnetic cleaning technique was used to compile the magnetostratigraphic map of the Tuanmo Group, Yunnan Province. By comparing the magnetostratigraphy with the magnetic polarity time scale, the authors have drawn the following conclusions :1. The age of Homo erectus yuanmoensis has been dated at 1.63=-1.64m.y.2. The Yuanmo Group was deposited at a time span of 1.53-3.12 m.y.These conclusions agree reasonably well with the data obtained from both mammalian fossils’and depositional rate.As judged from the magnetic zone of Yuanmo Group both the Gilsa and the Olduvai may with confidence be regarded as two separate and independent events in spite of the short interval, namely 0.01-0.02 m.y. separating them.So far as we know, the Yuanmo Group is the first geologic unit in the world, that records the two events concerned. |
