Short summary
Known as black smokers, sulfur-rich hydrothermal vents expel hot metal-rich water (~ 400°C). These extreme environments host micro-organisms capable of living at over 100°C. But to date, we do not know whether these microorganisms influence the formation of hydrothermal vents. The comparative study of minerals along the chimney wall is an essential step in determining whether microorganisms may have colonized and influenced mineral formation in certain parts of the chimney.
