Abstract

Massive charnockites from the Yercaud area in Tamil Nadu show petrographic evidence for post-metamorphic deformation. Fluid inclusion studies indicate a change in densities from 1.06 - 1.03 g/cm³ in the early carbonic inclusions to 1.17 - 0.90g/cm³ in the late carbonic inclusions. The wide range of density variations within each generation of fluids suggest that the syn-metamorphic fluids captured within inclusions could have been preferentially leaked out during post-metamorphic deformation.
