摘要：
We propose a method for dating Baikal deep-water sediments from the ratios of radioactive isotopes of Th and U in various fractions of the authigenic pan of the sediments. We have determined the Th-U age of six horizons of the borehole BDP-96-2 and the average parameters of gravitational consolidation of the sediments, The extrapolated Th-U ages show a good correlation with paleomagnetic data throughout the core of BDP-95-2.
