The fission-track technique was used to date nine samples of volcanic glasses from ash layers at Deep Sea Drilling Project Site 436. Age varied from 0.138 (+0.067 -0.063) m.y. to 12.9 (+2.11 -2.61) m.y. We annealed Sample 436-14-3 and corrected the age of annealed fossil tracks in the volcanic glass according to the resultant data. We found small differences between our age data and preliminary paleontological age data. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.823065"! ** Sediment depth is given in mbsf. Errors of Ps and Pi include errors in the count of the tracks and errors from uneven packing of grains in the mount.
