News Analysis: Ringwoodite, an Olivine Mineral thought to be in the Earth’s Core is viewed to help evidence a Billion Billion Tons Of Water in the Core. In Brazil, a Diamond discovered there had the Element therein. Included was 1.5% of its weight in water. That percentage extrapolated against what is estimated to be the Ringwoodite Deposits present the large Earth’s Core liquid estimate.
There is no present possibility of drilling into the depths of the Earth’s Core to test for Ringwoodite. “Miraculously” the Diamond was ejected through cracks in the Core up to the Earth’s Surface.
The Water Estimate of the Earth’s Core may lead Geologists towards solving questions about Continental Drift, Earthquakes, Volcanism, and the like.
One small Rough Diamond may lead to Enormous Answers for Mankind.
Reality.
