N2 - 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 degrees, I = 21.6 degrees, k = 22.3, alpha (95) = 5.2 degrees. The corresponding palaeomagnetic pole of 39.7 degreesN, 221.1 degreesE (D-P = 2.9 degrees, D-m = 5.5 degrees) is proposed as a 'key pole' for 1790-1770 Ma for Fennoscandia.
