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.

As Though They Had Never Been

"Besides this, however, many of their discoveries [the ancients] were ultimately lost to the world, some, as at Alexandria, by fire -- the bigoted work of a Mohammedan conquerer -- some by irruption of barbarians; and all were buried so long and so completely by the night of the dark ages, that they had to be rediscovered almost as absolutely and completely as though they had never been." -- Oliver J. Lodge, physicist, Pioneers of Science, 1893
