Delhayelite

Delhayelite is a rare mineral, a layered silicate. It has colorless and gray colors. The mineral received its name in 1959, when Th. G. Sahama and K. Hytönen named it in honor of the Belgian geologist Fernard Delhaye (1880-1946), who first conducted a geological study of the North Kivu province in the Congo (Zaire).
