Alkali olivine basalts of Jungel metavolcanic suite in Bijawar greenstone belt of Central India display various morphologies of quench crystals indicative of rapid cooling or supercooling. There is resemblance between crystal growths of the present area and those described from submarine basalts and experimentally produced crystals under disequilibrium conditions. Stratigraphy, structural and petrographic characters of these rocks demonstrate that they represent an ancient oceanic crust.
