A multidisciplinary approach to characterise the Early-Middle Holocene palaeoen...
Costa, Ana Maria; Freitas, Maria da Conceição; Jiménez-González, Marco A.; Jiménez-Morillo, Nicasio T.; Barrocas Dias, Cristina; Val-Péon, CristinaIn this paper we present the results of a multidisciplinary study performed in the Carrasqueira valley, a tributary of the River Sado (SW Portugal), aimed at characterising the Holocene environmental conditions during the late Mesolithic occupation of this valley. Our findings are based on a 13.5 m long sediment core (Arez3) collected on the alluvial plain close to a late Mesolithic shell midden, the Arapouco s...

Quantitative forecasting black (pyrogenic) carbon in soils by chemometric analy...
De la Rosa, José M.; Jiménez-González, Marco A.; Jiménez-Morillo, Nicasio T.; Knicker, Heike; Almendros, GonzaloA detailed and global quantitative assessment of the distribution of pyrogenic carbon (PyC) in soils remains unaccounted due to the current lack of unbiased methods for its routine quantification in environmental samples. Conventional oxidation with potassium dichromate has been reported as a useful approach for the determination of recalcitrant C in soils. However, its inaccuracy due to the presence of residua...
