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.
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.
