An unusual new mineral inside a diamond discovered by Alberta’s student

25 september 2019

A diamond with a new unusual inclusion was recovered from a mine in South Africa, phys.org reported.  The discovery was made by a Ph.D. student at the University of Alberta.
«The mineral—named goldschmidtite after Victor Moritz Goldschmidt, the founder of modern geochemistry—has an unusual chemical signature for a mineral from Earth's mantle,» Nicole Meyer, a graduate student in the Diamond Exploration Research and Training School, was quoted as saying.
"Goldschmidtite has high concentrations of niobium, potassium and the rare earth elements lanthanum and cerium, whereas the rest of the mantle is dominated by other elements, such as magnesium and iron," said Meyer.
"For potassium and niobium to constitute a major proportion of this mineral, it must have formed under exceptional processes that concentrated these unusual elements."
The goldschmidtite might have formed about 170 kilometers beneath Earth's surface, at 1,200 C.
"(The discovery) gives us a snapshot of fluid processes that affect the deep roots of continents during diamond formation," Meyer's co-supervisor, Graham Pearson, was quoted as saying by the agency. "This one is here to stay."
