Abstract: Russian programmes on radioactive waste management consider a possibility to organize an underground laboratory and subsequently an underground repository for intermediate- and high-level wastes in the vicinity of the Mayak radiochemical plant in the Urals. Effusive rocks widely abundant in the region are of interest among rocks potentially suitable for these purposes. These rocks are studied at different aspects of geology, geochemistry, geophysics and hydrogeology for the assessment of the rocks' suitability and siting the repository. In this work are considered first results on geochronology - the isotope dating of effusives by the K-Ar and Rb-Sr methods, as well as on some aspects of geochemistry - a study of volatile components of effusive rocks.
