Abstract
Granulite facies metapelites at Koliacode in the Kerala Khondalite Belt show compositional bands of cordierite, spinel, sillimanite and biotite alternating with quartz-feldspar rich bands. Reaction textures involving cordierite and garnet show evidence for decompression. Mineral phase equilibria computations provide temperatures of ca. 700-750C and pressures of 4.5-5.0 kbar. Spinel in these rocks is remarkably enriched in Zn (ZnO up to 9.4 wt. %). The metamorphic P-T conditions and mineral reactions indicate that the terrain underwent rapid and near isothermal decompression.
