Abstract: The physico-chemical conditions under which the pegmatite dyke No. 3 was formed were discussed in the light of fluid-melt inclusion evidence. Our results lend support to the frac-tionation of hydrothermal solutions from magma. For the pegmatite dike No. 3, the magma-derived hydrothermal solutions are dominated by NaCl + CO2 + H2O.
