Journal of the Geological Society of India, 2019 ABSTRACT Based on the field relations, associated rock types and age, the carbonatite-alkaline rock complexes of India, that are spatially related to deep main faults, rifts and shear zones, have been classified in to two major groups, namely: 1. Middle – late Cretaceous, subvolcanic – volcanic complexes (Amba Dongar, Siriwasan, Swangkre,
