Table 3. Sedimentation rates measured with the MEM from seven selected tablets, their physical environmental characteristics and bio- and lithofacies. Estimates of the mean
yearly accumulation were calculated from the sum of the means of the cool and warm periods. The total accumulation includes the first colonization values
