Experiments at a temperature of 800°C and a pressure of H-C-O fluid of 200 MPa under moderately reducing conditions (magnetite stability field) revealed the occurrence of superliquidus nanocluster cryptic and contrasting phase separation of a quartz-feldspar type in Li-F granite melts of the Podlesi cupolas (Czech Republic) with F, P, and H2O contents approaching the natural values. Similar to natural observations, ore components (W and Sn) were accumulated in the experimental samples in melts enriched in P and F.
