| Popis: | As a tribute to Bruno Lombardo, our senior co-worker who sadly passed away in 2014, the geologic setting and metamorphic evolution of the first eclogites discovered in the Eastern Himalaya are summarised in the context of U-Pb analytical results from the original granulitized eclogite samples. These eclogites occur at the top of the Main Central Thrust (MCT) zone in the Ama Drime Range (Arun - Phung Chu Valley), southeastern Tibet. The eclogites record five superposed metamorphic stages: a first eclogite-facies stage ( P > 1.5 GPa, T > 580°C), two granulite-facies stages at decreasing pressure ( P = 0.8–1.0 GPa, T > 750°C; P ~ 0.4 GPa, T ~ 750°C), an amphibolite-facies stage ( T = 700°C, P = 0.4–0.6 GPa) and a late retrogression stage ( T < 690°C, P |
