Abstract

A second occurrence of non-metamict davidite has been found in the Kirumba syenitic massif, Kivu, Rep. of Congo (Kinshasa). Its properties are described. Its geochemical data support the hypothesis of a genetic relationship between the Kirumba massif and the alkaline complex with carbonatites of Lueshe.
