Figure F10. Hole 1095B. Spectral maps for (A) the thorium/potassium ratio and (B) the natural gamma ray logs. The presentation is the same as Figure F7. On the spectral map A, the green, pink, and blue heavy lines, respectively, represent the Milankovitch 100-, 40-, and 20-k.y. periods, computed using the age model deduced from paleomagnetic data. The blue and dark blue dashed lines, respectively, represent the Milankovitch 20-k.y. period, computed using the age models deduced from diatom and radiolarian data.
