Abstract
Eclogites in Choloktor suite are petrographically divided into two types, i.e. glaucophane-bearing and glaucophane-free eclogites. Pelitic schists from the Atbashy suite consist mainly of quartz, garnet and chlorite with minor albite, phengite, epidote and carbonate. There are two kinds of garnets, fine-grained garnet and porphyroblastic garnets. High Si contents in phengites from pelitic schists suggest a high-pressure metamorphism of the Atbashy suite.
