Answer & Solution
Explanation :A Ph.D. student at the University of Alberta has discovered a new and curious mineral inside a diamond unearthed from a mine in South Africa. The mineral—named “goldschmidtite” in honor of Victor Moritz Goldschmidt, the founder of modern geochemistry—has an unusual chemical signature for a mineral from Earth’s mantle, explained Nicole Meyer, a graduate student in the Diamond Exploration Research and Training School.
“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 study, “Goldschmidtite, (K,REE,Sr)(Nb,Cr)O3: a New Perovskite Supergroup Mineral Found in Diamond from Koffiefontein, South Africa,” was published in American Mineralogist.
