Петромагнитные данные изменения природной среды голоцена в бассейне озера Чистое (Северное Приохотье)
The results of a comprehensive study of Lake Chistoye basin sediments are presented. Magnetic and mineralogical characteristics of various granulometric fractions of deluvial deposits, modern surface bottom sediments, and core materials have been studied. The relationship between the petromagnetic parameters of deluvium and lake sediments is shown. The composition of magnetic minerals has been determined. The dependence of magnetic characteristics on the granulometric composition of sediments has been established. Scalar magnetic parameters in core sediments show wide-amplitude variations reflecting frequent changes in sedimentation conditions. Sediments with high values of MS, Js, Jrs might have been formed in the periods of cold climate, with intensive flow of detritus material into the basin.
