Type: article
Abstract: The results of two experiments on the interaction of fluorine-containing granite melt and calcite with the same initial composition of the dry batch and different regimes of volatile components are presented. It is established that in both cases, at the boundary of calcite and fluorine-containing granite melt at given p-T parameters, an intensive transfer of matter occurs. In addition to other components, W and Mo are transferred from the silicate melt to the carbonate part, where they are deposited as molybdenum-containing scheelite. Comparison of the obtained samples allows us to qualitatively assess the effect of the fluid composition in the studied system on the stability of the resulting phases and the possibility of transporting ore components.
