Mode of occurrence, petrography and geochemistry of the peralkaline-peraluminous A-type rhyolites of Siwana Ring Complex, western Rajasthan have been described. Based on these data, their petrogenetic modelling and tectonic implications have been constrained. The petrogenetic studies infer a low degree partial melting of a crustal source for the origin of rhyolites.
