Fig. 1

Approximate locations of sampling sites plotted with the Zn isotope variations seen in the different stratigraphic intervals (formations labeled in cartoon stratigraphic column). Errors of the Zn isotopes are 0.05 per mil and are not significantly larger than the red line with white boarders. The cross-hatched area indicates the layers that contain the K–Pg boundary.
