| Abstract: | Through a 1:50,000 regional geological survey and research,for the first time,disc-shaped macrofossils were discovered in the Liangshan Formation of the Yimen Group in the Yimen area of central Yunnan.Results:For the first time,disc-shaped macrofossils were discovered in the Liangshan Formation of the Yimen Group of Paleoproterozoic in the Yimen area of central Yunnan,which further enriched the types of early macrofossil groups in the Central Yunnan Paleoproterozoic.Conclusions:The large-area comparison of the Precambrian strata in the southwestern margin of Yangtze provides paleontological evidence.This preliminary report opens a new window for exploring the early development and evolution history of the Earth from 2.8 billion to 800 million years ago from different perspectives;it is of great value to the study of the early Earth,s environmental evolution and life evolution,and it is worthy of further exploration and research. |
