dc.description.abstract | Anthracological analyses of charcoal samples retrieved from Pit 16 of Perdigões (Reguengos de Monsaraz, Portugal), a secondary deposition of cremated human remains dated
back to the middle of the 3rd millennium BC, enabled the identification of 7 different taxa:
Olea europaea, Quercus spp. (evergreen), Pinus pinaster, Fraxinus cf. angustifolia, Arbutus
unedo, Cistus sp. and Fabaceae. All taxa are characteristic of both deciduous and evergreen Mediterranean vegetation, and this data might indicate that the gathering of woods
employed for the human cremation/s occurred either on site, or in its vicinity. However, considering both the large distribution of the identified taxa and data about human mobility, it is
not possible to conclusively determine the origin of the wood used in the cremation(s). Chemometric analysis were carried out to estimate the absolute burning temperature of woods
employed for the human cremation/s. An in-lab charcoal reference collection was created
by burning sound wood samples of the three main taxa identified from Pit 16, Olea europaea
var. sylvestris, Quercus suber (evergreen type) and Pinus pinaster, at temperatures
between 350 and 600 ˚C. The archaeological charcoal samples and the charcoal reference
collection were chemically characterized by using mid-infrared (MIR) spectroscopy in the
1800–400 cm-1 range, and Partial Least Squares (PLS) regression method was used to
build calibration models to predict the absolute combustion temperature of the archaeological woods. Results showed successful PLS forecasting of burn temperature for each taxon
(significant (P <0.05) cross validation coefficients). The anthracological and chemometric
analysis evidenced differences between the taxa coming from the two stratigraphic units | es |
