  1. Semi-quantitative concentrations of the average composition of the yellow paint layer derived from LA-ICP-MS using an interpolation between the count rates of a 1 ppb multi-element standard (ICP multielement standard solution XXI for MS, by Accustandard), and using the average count rate of Ca 44 over the white ground layer assuming the Ca concentration was 40 wt% here corresponding to pure calcite
  2. Using this assumption, the S and Sr concentrations of the white ground layer were found to be 0.8 and 1.6 wt%, respectively. All concentrations are in weight percent. The RSD uncertainties are probably not better than c. 20%
