| Research Abstract |
Coesite relics were discovered as inclusions in Cpx in eclogite and as inclusions in zircon in felsic and pelitic gneisses from Higher Himalayan Crystalline rocks in upper Kaghan valley, north-west Himalayas. The metamorphic peak conditions of the ultrahigh-pressure (UHP) eclogites are estimated to be 28.6±0.4 kbar and 757-786℃. The Himalayan UHP metamorphic rocks crops out a very thin layer (<100m) sandwiched between overlying and underlying medium to high-pressure metamorphosed units. This imply that the very thin UHP layer moved up from the mantle depth (95-120km) to the mid-crustal level (30-40km), then stopped and thermally altered the surrounding the Higher Himalayan Crystalline rocks.
