And that newfound substance could reveal unusual chemical reactions unfolding in the depths of the mantle, the layer of Earth that lies between the planet's crust and outer core.
Scientists unearthed the mineral from a volcanic site in South Africa known as the Koffiefontein pipe.

They named the newfound mineral "goldschmidtite" in honor of acclaimed geochemist Victor Moritz Goldschmidt, according to the study, published Sept. 1 in the journal American Mineralogist
The entire mantle is about 1,802 miles (2,900 km) thick, according to National Geographic, which makes the  (▪ ▪ ▪)
