• Precursor metamorphism

Eclogites occurring in the Neldy Formation or the Makbal district in the Kyrgyz Northern Tien-Shan are newly described The metamorphism of the eclogites is divided into two events, a precursor metamorphic event and a subsequent eclogitic metamorphic event The metamorphic conditions of the precursor event are represented by the amphibolite facies The peak metamorphic conditions of eclogitic event are estimated to be T = 550-610 degrees C and P = 22-25 kbars The prograde, peak and retrograde metamorphic conditions define a hairpin-type clockwise P-T path for the Neldy eclogues
