Quantification of calcareous nannofossils from the micro-sample MS04 disaggregated by the two micro-emulsions ME1 and ME2 at 20 °C or at 70 °C (“ME1-20” = Micro-emulsion 1 at 20 °C or “H2O-70” = Micro-emulsion 1 at 70 °C). MS04 disaggregated with water showed 0% of counted nannofossil and is therefore not shown in the graphic. The ratio of whole and broken nannofossils in the sample is expressed as the percentage of whole nannofossils. Ref is the value of this ratio in the original rock material
