Comment:
U-series dating of carbonates using method after Fietzke et al. (2005) and decay constants after Cheng et al. (2000) at the Low-Temperature-Isotope-Geo-Chemistry-Lab (LTIGC) of IFM-GEOMAR-Kiel.
M66-129: sample weight close to limit of applied balance, isotope ratios and age reasonable but concentrations are highly uncertain
M54-143: increased uncertainty on age constrains , due to high 232Th concentration combined with low 230Th/232Th activity ratio
