The study of the role of microbes and microbial processes in the field of geology and geochemistry
Geomicrobiology is the result of the combination of geology and microbiology. The field of geomicrobiology concerns the role of microbe and microbial processes in geological and geochemical processes and vice-versa. The field is especially important when dealing with microorganisms in aquifers and public drinking water supplies. Another area of investigation in geomicrobiology is the study of extremophile organisms, the microorganisms that thrive in environments normally considered hostile. Such environments may include extremely hot environments, extremely saline environments, or even space environments such as Martian soil or comets. Recent observations and research in hyper-saline lagoon environments in Brazil and Australia have shown that anaerobic sulfate-reducing bacteria may be directly involved in the formation of dolomite. This suggests the alteration and replacement of limestone sediments by dolomitization in ancient rocks was possibly aided by ancestors to these anaerobic bacteria. Some bacteria use metal ions as their energy source. They convert the dissolved metal ions from one electrical state to another. This reduction releases energy for the bacteria's use, and, as a side product, serves to concentrate the metals into what ultimately become ore deposits. Certain iron, uranium and even gold ores are thought to have formed as the result of microbe action.
