Abstract Modern techniques for detrital mineral provenance were applied to sediment core 96/12‐1pc from the Lomonosov Ridge in the central Arctic Ocean. The techniques include quantitative clay mineralogy analysis combined with determination of Nd, Pb, and Sr isotopes from clay fraction. The clay mi...
