Bacterial Remains in the Lower Proterozoic Red-Colored Quartzites

The discovery of numerous bacterial remains (including those morphologically similar to modern ironbacteria) in the lower Proterozoic red-colored quartzites of Shoksha, Karelia, and Bolshoy Tyuters Island of the Gulf of Finland, indicates a significant role of bacterial communities in the formation of hematite pigment in the studied rocks.

Automated summary

The presence of bacterial remains in the red quartzites of different regions in Russia suggests a significant contribution of bacterial communities to the formation of hematite pigment in these rocks.
