    • Selective Leaching of Shells for 14C Dating

      Although acid leaching of shell carbonates prior to 14C assay is usually desirable, under some circumstances it can worsen contamination by preferentially solving unaltered shell and thus increasing the proportion of secondary carbonate. The risk can be eliminated by monitoring the progress of leaching with the help of microscopy and x-ray diffraction.
