How Could Surface Minerals Get in Diamonds Found in The Deepest Depths of The Earth? – ScienceAlert

Diamonds that formed hundreds of kilometers deep below Earth’s surface contain traces of chemical reactions that took place on the bottom of the ocean.
Given that the bottom of the ocean is just 11 kilometers (6.8 miles) down at its deepest point, this may seem rather odd but those diamonds are a really valuable clue for understanding the exchange of material between Earth’s surface and its crushing depths, researchers say.
“Nearly all tectonic plates that make up the seafloor eventually bend and…
