  1. Experimentally and theoretically, that assumption seems justified.
  2. On the one hand, the half life should be short enough so that a measurable amount of the daughter element has formed.
  3. At locations B and C, deposition stopped at some time in the past.
  4. Note that although the thicknesses vary from location to location, the ratios of thicknesses remain constant.

To determine the age within one year of any layer, all that needed to be done was to count the number of layers down to the artifact and that was equal to the absolute age of the artifact's burial.

Similarly, by pattern matching, five layers in the series at B can be correlated with five layers at the top of C.
