Abstract Eclogites characterized by the omphacite - garnet - quartz - rutile ± phengite assemblage are reported for the first time in the Himalayan belt. They occur in the High Himalayan Crystallines (HHC) and Tethyan metamorphic units of northern Pakistan. The eclogites formed at T ≈ 650 ± 50°C and P ≈13 - 18 kbar, and represent the deepest rocks derived from the Indian plate known so far. They show an incipient decompressional re-equilibration which probably occurred at decreasing temperatures, in contrast with the exhumation path at constant or increasing temperatures of the HHC in India and Nepal.
