The study of the riebeckite syenite from Idamakallu-Racherla area shows interesting textural and microstructural features. Based on the petrographical and petrochemical evidence, it is surmised that a rock, which was originally a hornblende syenite, has been transformed into riebeckite syenite through soda-metasomatism. The way in which the mineral transformations took place and the secondary minerals have developed is discussed.

X-ray study of the graphitic clay schist from Hunkund (Ganacharpur) has shown that graphite is crystalline and not amorphous as inferred by earlier workers. The geochemical study indicates that the graphitic clay schist has resulted from the metamorphism of carbonaceous clays.
