In Geology Institute was held all-republican scientific seminar for branch of Earth Sciences. In the seminar Chiragov M.I. from BSU speeches about  “Structural - crystallochemical aspects of mineralogical-geochemical research (the example of Ca-and Tr- silicates)”.

The report presents the results of hydrothermal synthesis, structural interpretation and comparative crystallochemistry of synthetic and natural calcium and rare earth silicates. The data enable to explain the direction of phase transformation, phase formation or mineralization.
