Abstract:
Compound-specific radiocarbon data have been obtained from terrigenous biomarkers, i.e. high molecular weight n-alkanoic acids (n-C26:0 alkanoic acid) and high molecular weight n-alkanes (n-C23, n-C27 and n-C29 alkanes). The F14C has been corrected for procedural blanks associated with the isolation of the biomarkers. The data compilation contains the measured (AMS-results) as well as the blank-corrected F14C values. The 14C-data are reported with the 1sigma uncertainty.
