| Sumario: | [EN] An ATR-FTIR-based analytical methodology aimed to obtain information on the native wood, charring intensity, and age of archaeological charcoal is described. This is based on the determination of transmittance ratios calculated from transmittances at selected pairs of wavenumbers. The method is applied to a set of charcoal samples recovered in different archaeological sites from the western Mediterranean area, identified as Pinus halepensis and Quercus sp. evergreen. The method provides unambiguous discrimination between these two types of charcoal and allows the construction of age calibration graphs for dating charcoals from Pinus halepensis and Quercus evergreen species. A kinetic modeling of charcoal aging based on cellulose degradation studies is provided. |
