摘要

在前寒武纪剖面，太古宙方解石碳酸盐岩在元古代向镁质和铁质转变。这与蓝藻的大量发育有关，蓝藻对二氧化碳的吸收和氧气的生成导致了元古代太古宙碱性氧化的酸性还原条件发生了变化。

Geochemical environments of the Archean-Proterozoic

In the Precambrian section, there is a change of Archean calcite carbonate rocks to magnesia and ferrous in the Proterozoic. This is correlated with the massive development of cyanobacteria, the absorption of which carbon dioxide and the generation of oxygen, led to a change in the acidic reduction conditions of Archaean alkaline oxidizing in the Proterozoic.
