It seems that we are closer to Jules Verne’s idea of an ocean inside the Earth. Yes, you heard right. Although you know that 70% of the entire earth’s surface is covered with water, most of which is present in the five oceans. An international study has now found water deep inside the blue planet’s interior.
A team of scientists from the Frankfurt Institute for Geosciences at Goethe University in Germany analyzed a rare diamond formed 660 km below the Earth’s surface using Raman spectroscopy and FTIR spectrometry and came across some incredible results.
The study showed that the transition zone between Earth’s upper and lower mantle contains “significant amounts of water,” confirming a long-held theory that the planet’s water cycle involves the Earth’s interior.
Prof. Frank Brenker of the Institute for Geosciences says: “In this study, we have shown that the transition zone is not a dry sponge, but contains a significant amount of water. This brings us one step closer to Jules Verne’s idea of an ocean within.” The difference is that there is no ocean down there, but moist rock that is neither wet nor dripping with water.’
Analyzes revealed that the stone contains numerous ringwoodite inclusions – which exhibit a high water content. Furthermore, the research group managed to determine the chemical composition of the stone. It was almost exactly the same as virtually every fragment of mantle rock found in basalts anywhere in the world.
