Abstract
U-Pb age determinations by ion microprobe on zircons from two tuff samples within the Neoproterozoic-early Cambrian successions in Poland are presented. One sample, from the Kaplonosy borehole is within, or conformably below, rocks that contain the Sabellidites-Vendotaenia fossil assemblage of the Upper Vendian. The second sample is from the Ksiaz Wielki IG-1 borehole, from rocks that were referred alternatively to the early Cambrian or to the Vendian on lithostratigraphic evidence. -from Authors
