‘Southern India now becomes readily intelligible. In the 
Dharwar area adjacent to the Charnockite area of Southern 
India, the Dharwar Series is represented almost solely by its 
igneous members; consequently, most of the rocks representing 
its intensely metamorphosed facies, in the Charnockite Series, 
are also igneous. In the north-eastern portion of the Peninsula, 
the Dharwars consist of alternations of igneous and sedimentary 
strata; their intensely metamorphosed representatives in that 
sa rt of the Peninsula, consist of alternations of igneous 
Charnockites and sedimentary Khondalites.
