A palaeomagnetic study of the Vepsian sandstones of the upper part of the Shoksha Formation has revealed a stable remanence. Rock magnetic and mineralogical studies suggest diagenetic haematite as the main carrier of this remanence. Two magnetic polarities with a regular stratigraphic zonation have been found. The reversal test is positive. The tilt-corrected palaeomagnetic direction is: N=36, D=354.3°, I=21.6°, k=22.3, α95=5.2°. The corresponding palaeomagnetic pole of 39.7°N, 221.1°E (Dp=2.9°, Dm=5.5°) is proposed as a `key pole' for 1790-1770Ma for Fennoscandia.
