Abstract
⺠New SHRIMP ages for garnet pyroxenite from Chu-Yili Mountains of South Kazakhstan reveal so far unknown early Paleozoic HP belt with a peak metamorphism at â¼490 Ma. ⺠Chemical composition of the garnet pyroxenite points at an ultramafic mantle protolith. Block-in-matrix structure of the belt implies exhumation in subductional channel. ⺠Upper Cambrian arc related granodiorite dated as 509 Ma delineates magmatic arc in the NE of the HP belt. ⺠The HP belt was formed in subductional and collisional setting due to convergence of Anrakhai arc and North Tianshan microcontinent with subduction towards the NE.
