HIGHLIGHTS
- who: C. Mouraux from the CNRS have published the paper: Assessing the carbonisation temperatures recorded by ancient charcoals for u03b413C-based palaeoclimate reconstruction, in the Journal: Scientific Reports Scientific Reports
- what: The authors show that post-depositional oxidation-a subsequent rise in %O-can bias the determination of carbonisation temperatures through %C. By reducing the %C, post-depositional processes can therefore lead to an underestimation of carbonisation temperatures implying in turn, an inappropriate correction of carbonisation-induced 13C fractionation.
SUMMARY
The %C-based thermometer is therefore not suited to assess the . . .
