The Jahaj-Govindpura Volcanics - the youngest formation of the Rajalo Group in the Bayana sub-basin, comprises lava flows, agglomerates, volcanic breccias, tuffs, and quartzite interbeds. Volcanics have been fed by feeder dykes which clearly cut the underlying rocks. Plots of geochemical data from this volcanic suite reveal that compositionally they are transitional between aikali basalt and tholeiite. They resemble high-K2O continental tholeiites.

Volcanics have been fed by feeder dykes which clearly cut the underlying rocks. Plots of geochemical data from this volcanic suite reveal that compositionally they are transitional between aikali basalt and tholeiite. They resemble high-K2O continental tholeiites.
