- •
Metamorphic history of highly retrogressed eclogites from Stak massif is examined.
- •
Some garnet grains contain omphacitic pyroxene inclusions.
- •
Zircon shows ca. 32 Ma, which is younger than peak age of Himalayan UHP eclogites.
- •
Stak eclogites resided at lower crustal depth and heated by nearby hot massif.
- •
Stak eclogites experienced different history from other UHP eclogites in Himalaya.
