Abstract:

Plant wax alkanes from Tarn 2, Mt. Usborne, East Falkland extracted from tar2-18-1 with piston corer in Spring 2018. Data is plotted by depth of the piston core and age. Plant wax alkanes are reported as carbon chain length, concentration (ug/g of sediment), and stable isotope (hydrogen-dD VSMOW; carbon-d13C VDPB).
