...., Phillips and Onstott 1986 ). Diamonds are known to occur in diverse rock types including kimberlite, orangeite, lamproite, aillikite and ultramafic lamprophyre. Thus, an important aspect of this study is the choice of nomenclature which would best describe the Abloviak dykes. The data are compared...
