Granulite (felsic)
The common metamorphic facies. The boundaries between the facies are depicted as wide bands because they are gradational and approximate. P-P = Prehnite-Pumpellyite facies.

Ultrahigh-temperature metamorphism revealed by felsic granulite
We report a UHTM event in the Lhasa Block, identified from felsic granulite xenoliths in Sangsang near the Tangra Yum Co Rift (TYR) of southern Tibet. These xenoliths exhibit a mineral assemblage of garnet + rutile + quartz + K-feldspar + plagioclase ± kyanite.

Response of trace elements to partial melting of felsic crust …
Petrological studies of granulite-migmatite-granite terranes demonstrate that partial melting and melt extraction are the two predominant mechanisms for chemical differentiation of the continental crust (e.g., Brown, 2013; Sawyer, 1998).

Granulite (felsic)
The rocks with >30% mafic minerals (dominantly pyroxene) may be called mafic granulites, those with <30% mafic minerals (dominantly pyroxene) may be called felsic granulites. Granulite may exhibit a crude gneissic structure due to the parallelism of flat lenses of quartz and/or feldspar. The texture is typically granoblastic.

Ultrahigh-temperature metamorphism revealed by felsic granulite
The Himalayan-Tibetan orogen experienced extensive thermal disturbance during the Indian-Asian collision, yet evidence for ultrahigh-temperature metamorphism (UHTM, >900 °C) remains scant. We report a UHTM event in the Lhasa Block, identified from felsic granulite xenoliths in Sangsang near the Tangra Yum Co Rift (TYR) of southern Tibet.
