Description	Felsic granulites from the Kutná Hora complex in the Moldanubian zone preserve mineral assemblage that records transition from early eclogite to granulite facies conditions, and exhibits leucocratic banding, which is interpreted as an evidence for melt loss during the decompression path. Garnet cores grew during omphacite breakdown and phengite dehydration melting at 940 °C and 2.6 GPa, following by decompression heating to 1020 °C and 2.1 GPa. The maximum melt productivity was 26 and 18 vol.%, respectively, at peak temperature ~1.05–0.75 H2O wt.%, prior to the melting. The preservation of prograde garnet-rich assemblages required nearly complete melt loss (15–25 vol.%), interpreted to have occurred at 1000–1020 °C and 2.2–2.4 GPa by garnet mode isopleths, followed by crystallization of small amounts of residual melt at 760 °C and 1.0 GPa. Phase formation and melt productivity were independently determined by experiments in the piston-cylinder apparatus at 850–1100 °C and 1.7–2.1 GPa.
