ABSTRACT. Black, opaque grains of a spinel whose composition is (Mg2TiO4) 85.8, (MgFe204) 0.4 (FeFe204) 13.8 (mole %) coexist with a MgA1204 spinel and geikielite in a periclase-forsterite marble that has been thermally metamorphosed against an alkalic ultra-mafic intrusion of Caledonian age in the...
