摘要
With undertaking the sequence stratigraphic study on the Baiguoyuan section, the Doushantuo Formation and the Dengying Formation which were formed after the Nantuo ice age could be grouped into one second-order sequence. The Doushantuo Formation contained phosphorites represented a strong transgressive activity after the Nantuo ice age. With the application of geochemistry and studying on phosphatic series, the results indicate that organic matter plays an important part in the formation of phosphorite.
