The Malani volcanics of Gurapratap Singh and Diri belong to a basalt-andesite -daciterhyolite association of Precambrian age. The preponderance of rhyolites over basic and intermediate rocks is a significant feature of the area. The rhyolities are characterised by chemical features, which indicate their A-type affinity. The study rules out their cogeneticity and suggests the crustal involvement in the genesis of Malani rhyolites.
