The magnetic susceptibilities measured in 220 metamorphic rocks collected over a traverse distance of about 2500 km, from South Indian granulite terrain, varied over a wide range. The wide variation in the susceptibilities, 6-4420×10-6 emu/cc is explained in terms of changes in magnetic mineralogy during prograde and retrograde metamorphic processes.
