Genesis of chrysoberyl in the pegmatites of southern

The pegmatites are thought to have derived from the residual melts of granitic liquids formed by partial melting of the khondalites. In the absence of pyrometasomatic, desilication or aluminium-contamina-tion processes, the genesis of chrysoberyl isexplained by the CO 2 activity in residual melts. This model is at variance with the known concepts and may also explain the genesis of
