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.
