Investigating Hydrogen Isotope Variation during Heating of <i>n</i>-Alkanes under Limited Oxygen Conditions: Implications for Palaeoclimate Reconstruction in Archaeological Settings.

In xylem samples, there is a decreasing trend toward 2 H depleted values between 150 and 250 °C of ~19‰ (nC 27 ) and ~35‰ (nC 29 ) despite an increase in total n -alkane concentration in these samples.
