Yaxcopoil-1 drillhole, interval between reworked ejecta and basal Paleocene background infill, 793.85-794.60 m

Transition impact ejecta to post-impact Paleocene crater infilling (taken April 26, 2002 at UNAM Mexico). Interval 794.01-794.41m (box177, row 4). Base Paleocene with the clay layer (000031) presumably enriched in iridium is at 794.11m

Core halves(pieces) of the interval 794.60 to 793.85 below the drillrig floor (794.41m is the correct depth between Coreboxes 178 and 177) Images taken at the Vrije Universiteit Amsterdam on July 24. The numbers are the sample page labels, as used during the sample party in april 26-May 3 at UNAM, Mexico, and should correspond to sample numbers in the CSDP-DIS database. (See below)
