Calcite Cement

U-Pb radiometric dating is the only absolute geochronometer applicable to diagenetic carbonates. However the most robust and accurate technique based on acid dissolution followed by isotope dilution remains inapplicable in many cases because of either low uranium or high common lead content or because of the impossibility of microsampling a single monogeneration diagenetic cement of interest
