von Knorring, Sahama & Lehtinen (1969) published data on kornerupine found in 2 samples of a highly metamorphic gneiss said to come from "Inanakafy near Betroka, Madagascar". "Inanakafy" is most probably a misspelling and refers to the small village and commune centre of Ianakafy situated about 90 km along a dirt road West of Betroka.

Detailed Mineral List:
| ⓘ CordieriteFormula: (Mg,Fe)2Al3(AlSi5O18)Habit: oval-shaped monomineralic aggregatesColour: slightly bluishDescription: a very Mg-rich variety with ca. 7 mol. % of the iron component |
|---|
| ⓘ KornerupineFormula: Mg3Al6(Si,Al,B)5O21(OH)Habit: prismatic crystals up to 3-4cm long and 1cm thick. The prisms show the faces {100}, {010} and {110}. End faces are extremely rare and poorly developed. Only {111} could be identified. |
| ⓘ 'Orthopyroxene Subgroup'Habit: euhedral to subhedral crystals characterized by the pyramidal faces {211}. Faces {101} not visible.Colour: brownishDescription: The mineral represents a bronzite with (Fe, Mn): Mg = 15:85 and with Al largely substituting for Si. |
| ⓘ PhlogopiteFormula: KMg3(AlSi3O10)(OH)2Habit: mostly anhedral flakes up to 1cm, sometimes showing prismatic faces and, very rarely, showing poorly developed pyramidal faces.Colour: black |
| ⓘ 'Plagioclase'Formula: (Na,Ca)[(Si,Al)AlSi2]O8 |
| ⓘ SapphirineFormula: Mg4(Mg3Al9)O4[Si3Al9O36]Colour: slightly greenish blue |
| ⓘ SpinelFormula: MgAl2O4Colour: blueDescription: pure MgAl-spinel |
| ⓘ 'Tourmaline'Formula: A D3G6 (T6O18)(BO3)3X3Z Colour: black |
| ⓘ ZirconFormula: Zr(SiO4)Habit: euhedral crystals |
