In the Lithuania, a palaeomagnetic study of Upper Pleistocene and Late Glacial sediments at five sections has been carried out. The palaeomagnetic study of the varved clays in the Maskauka, Didžiasalis and Girininkai sections cover the time interval since 18,000 to 14,000 BP and Mančiagire section covers the time interval since 12,700 to 11,630 BP. The palaeomagnetic research of the Merkine (= Eemian) Interglacial sediments (Netiesos section) cover the time interval since 112.0š25 to 101.5š11.5 ka BP. The declination (D), inclination (I) and intensity (J) of the natural remanent magnetization of glaciolacustrine clays (Maskauka, Didžiasalis and Girininkai sections), as well as Merkine (=Eemian) Interglacial deposits (Netiesos section) and interstadial sediments (Mančiagire section) were measured. The result of these studies is presented in diagrams. The study reveals that considerable palaeomagnetic information can be obtained from the varved clays.
