iron to the ocean allowed the cyanobacteria

CYANOBACTERIA . For scientists this supply of iron to the ocean allowed the cyanobacteria, "blue algae" to proliferate. "Their metabolism requires ten times more iron than other photosynthetic organisms," explains Peter Swart, lead author of the study. Now these cyanobacteria produce calcium carbonate galore. This material makes up the exoskeleton of corals but also the platform diving from which emerge the Bahamas. This platform has a thickness of carbonates of 4.5 kilometers and formed by carbonate precipitation excreted by cyanobacteria during the last 100 million years.
