Oxygen, the atmosphere, and black smokers

20 November 2013

This is the third link that is reminiscent of Malaga Bay (remember the black smokers on the ocean bottom) – see http://phys.org/print303899664.html … a paper in Nature Geoscience by a team from the Norwegian Geological Survey claims oxygenation of the atmosphere and oceans came about two billion years ago. This also produced phosphorous – and phosphorus was the clue to the findings. Phosphorous is an important ingredient of life and all this popped out when the team were looking at rocks in Karelia (next door to Finland but in Russia) reputed to be two billion years of age. They say the formation of Earth's earliest phosphorite was influenced strongly, if not completely, by the activity of sulphur bacteria. In the modern world sulphur bacteria inhabit upwelling vents and seep areas known as 'black smokers' – so, is there some mileage in the Expanding Earth theory?
