Abstract
- Three kornerupine occurrences are reported in distinctive SiO<subscript>2</subscript>-poor, MgO- and Al<subscript>2</subscript>O<subscript>3</subscript>-rich paragneisses from the Namaqualand Metamorphic Complex in South Africa. Kornerupine coexists stably with phlogopite, cordierite, orthopyroxene, gedrite, sapphirine, sillimanite and plagioclase and, in sapphirine-free rocks, with spinel and corundum. Tourmaline of a texturally older generation than kornerupine is commonly present in the same samples.
