The Shuanghe garnet-bearing paragneiss from the Dabie ultra-high–pressure (UHP)
orogen occurs as an interlayer within partially retrogressed eclogite. A first UHP
metamorphic stage at 680°C, 3.8–4.1 GPa is documented by Zr-in-rutile temperatures coupled with phengite inclusions (Si = 3.55) in clinozoisite and grossular-rich
garnet. Relic matrix phengite and phengite inclusions in zircon rims display lower
Si of 3.42. Combined with garnet compositions and Ti-in-zircon temperatures,...[Show more]
