Two sediment sequences from a cave near Schoharie, N.Y., have been sampled for palaeomagnetic measurements. The nature of the palaeomagnetic records obtained was found to be similar to other North American records. A correlation can be made with lake sediment records back to 13,000 yr B.P., and with a sediment record from Bessette Creek in Canada for the period between ~ 23,000 and 30,000 yr B.P. During both periods the dominant long-term trend of the VGP path has been that of anticlockwise motion, but during the last 13,000 years there has been more superimposed short-term clockwise motion than during the earlier period. Magnetic properties of the sediments suggest that magnetite is the dominant magnetic mineral and this is confirmed by the Mössbauer spectra of both the sediments and magnetic extracts. Mössbauer measurements on the magnetic extracts also detected the presence of a small amount of haematite.
