Carbon In Deep Mantle

An old rediscovery = science in cryptomnesia.

Science Daily: Carbon Cycle Reaches Earth's Lower Mantle: Evidence of Carbon Cycle Found in 'Superdeep' Diamonds From Brazil.

ScienceDaily (Sep. 15, 2011) — The carbon cycle, upon which most living things depend, reaches much deeper into Earth than generally supposed -- all the way to the lower mantle, researchers report.

The findings, which are based on the chemistry of an unusual set of Brazilian diamonds, will be published online by the journal Science, at the Science Express Web site, on 15 September. Science is published by AAAS, the non-profit, international science society.

"This study shows the extent of Earth's carbon cycle on the scale of the entire planet, connecting the chemical and biological processes that occur on the surface and in the oceans to the far depths of Earth's interior," said Nick Wigginton, associate editor at Science.

"Results of this kind offer a broader perspective of planet Earth as an integrated, dynamic system," he said.

Plate Tectonics? You now support Plate Tectonics? Neat.

Deep mantle carbon is not subduction.

Did you read the whole article?

The carbon cycle generally refers to the movement of carbon through the atmosphere, oceans, and the crust. Previous observations suggested that the carbon cycle may even extend to the upper mantle, which extends roughly 400 kilometers into Earth. In this region, plates of ocean crust -- bearing a carbon-rich sediment layer -- sink beneath other tectonic plates and mix with the molten rock of the mantle.

The article is indeed "subductionist" and "biotic".

That is better:
