- Аннотация: Despite the long history of studying of the complex, the questions of the relationship between the P-T-t conditions of formation of UHP rocks, the geochemistry of their initial compositions (protoliths), the periodicity and the trends of metamorphic processes, the geodynamic development of the region remain unclear. In this paper, an attempt is made to generalize available data and to carry out a comprehensive study of UHP rocks of the complex: to determine the nature and geochemical history of basalt protoliths, to find the sources of their initial material, to decipher the periodicity and features of the evolution of metamorphism in different stages of the region development. Combined with microprobe data on the composition of coexisting minerals and physico-chemical parameters of metamorphism, calculated on their basis (Fedkin et al., 2017), we hope to decipher the P-T-t history of the complex, and to estimate the character of heat flux both at the stage of its UHP immersion and during the exhumation. For this purpose, high-quality XRF and ICP-MS analyzes of gross composition were performed for 18 samples of garnet-bearing rocks. P-T conditions for their formation were calculated on the basis of detailed microprobe analyzes using traditional cation-exchange thermometry and modeling phase equilibria.
