The laboratory of petrology has been formed in 1967 from the group of researchers – followers of prof. N.G. Sudovikov. The main goal is the study of the laws of evolution and tectonic localization of metamorphism and metasomatism. Laboratory staff investigate interaction of fluid flows with metamorphosed rocks and magmas at the level of the lower crust and upper mantle: geology, origin and sources of fluid, its transport properties, physico-chemical parameters and evolution, role in petro- and oreogenesis. The following methods and approaches are used:
- Structural analysis of igneous and metamorphic rocks and identification of the geodynamic environments and the sequence of events on the basis of exploration and analysis of kinematic indicators.
- U-Pb isotopic dating of metamorphic processes using accessory (zircon, baddeleyite, monazite, apatite, etc.) and rock-forming (garnet) minerals.
- Investigation of Sm-Nd, Rb-Sr, Lu-Hf, Re-Os isotope systems in order to reveal sources of magmas and fluid flows and isochronous dating of minerals and whole rock samples.
- Investigation of the geochemistry of light isotopes (O, H, C, S) which helps to find the deep matter of fluids and magmas. Development of the theory of fractionation of stable isotopes during crystallization of minerals from fluids and melts.
- Investigation of the laws of crystal/fluid and crystal/melt distribution of rare and ore elements. Development of models of partial melting, of formation of magmatic chambers and magmatic differentiation.
- Investigation of distribution of ore deposits in zones of shear deformations and metasomatism.
- Thermometry and barometry of metamorphic rocks using internally consistent bases of thermodynamic data and techniques developed by the laboratory staff.
