| Abstract: | Organic geochemistry and biomakers of some Lower Cambrian high-selenium formations in China are studied, the results show that main organism contain the low and aquatic homonemeae in all these high-selenium formations (HSF), and some biomakers indicate sedimentary environment might mainly be close and anoxic condition. At the same time, based on geological facts, it is considered that reductive sedimentary environment is advantageous to growth and preservation of homonemeae, and enrichment of selenium is closely relative to bloom of homonemeae. |
