| Sumario: | [EN]The present work examines the possibility that the tin-bearing mineralizations spatially associates to the Ricobayo batholith might have originated by fractionated crystallization. Accordingly, a study was made of the characteristics shown by the distributions of Ba, Rb and Sr together with the relationship to the theoretical distributions generated by the model of granitic evolution by fractionated cristallization. The results suggest that Sn mineralizations can not only have been generated as a result of such a process and that the activity of alkali-rich volatiles must have played and essential role in this. |
