The laboratory studies the history of climate, regularities and mechanisms of the dynamics of the natural environment in the Holocene and Pleistocene. For this, geological and biological proxy indicators are used. Theoretical and experimental studies are carried out in the field of magnetism of natural geological and biological objects with an assessment of their physical parameters and origin. Equipment and methods for diagnosing various magnetic components are being developed.
