The course is based on the application of the principles of chemistry to understand geological processes on our planet. The theoretical material covers a wide range of topics divided into two thematic sections: a) Processes in the core-mantle-crust system, and b) Processes in the crust-hydrosphere-atmosphere system. The laboratory exercises aim to develop both cognitive and practical skills and include the analysis of geochemical data from the literature and experiments in the chemistry laboratory. Fieldwork is conducted in a geochemically interesting area with the aim of recognizing geochemical processes in the field and presenting methods of outdoor sampling of geochemical media.
