At 750°C and a pressure of 1 kbar, an experiment was carried out simulating the contact-reaction interaction of calcite and a deeply differentiated fluorine-containing granite melt. The water content in the system did not exceed 10% of the dry charge mass. The possibility of interaction of magmatic melt with calcite is shown. The experimental products contain a zoned column composed of liquid phases along with crystalline minerals. In the apocarbonate part, the newly formed phases are represented by cuspidine, quartz, wollastonite, grossular and the non-crystalline carbonate-fluoride phase LCF. Phase parageneses in the zones of the apocarbonate part of the column vary depending on the ratio of CO2 and HF activities. In the silicate part, aluminosilicate glass, alkali feldspar, and plagioclase of variable composition were found. Silicon and fluorine are intensively transferred from the silicate to the carbonate part, and calcium in a small amount is transferred in the opposite direction.
