We have investigated metamorphic mineral assemblages of pelitic and psammitic rocks from the Chitradurga Schist Belt in the Dharwar Craton, southern India. Pelitic and psammitic rocks are characterized by biotite-muscovite assemblage with minor muscovite/muscovite-chlorite assemblages. Recently, Kiran et al. (2022) estimated the metamorphic conditions for carbonate rocks from the CSB. Incorporating these recent updated data, we discuss the progressive metamorphism of this part of Dharwar Craton.
