U-Th isotope systematics and light stable isotope data of carbonate enriched sediments at MASOX site (methane seepage off Svalbard) at sediment core MSM21/4_657-1
Values with # mark highly unreliable ages characterized by uncertainties larger than the deduced age or even dominated by 230Th correction values as well as isochron approaches based just on 2-point reference lines. Therefore, the latter may not provide any proof for the petrographic postulation of...
