Resumen
Fluvial tufa build-ups located in the Queiles, Val and Las Parras del Martín river valleys (Iberian Range, NE Iberia), are investigated following radiocarbon dating, palynological and anthracological analyses. The studied tufa deposits have been framed within the Early-MidHolocene (ca. 9500 to 4000 cal yr BP) in agreement with regional palaeoenvironmental evidences. The obtained palaeobotanical results highlight the existence of dense riparian woodland where diverse broadleaved trees defined the main vegetation features in the river valleys.Deciduous and evergreen oaks were the main spread regional forests accompanied by many warm-loving taxa. Pinewoods were usually confined to high-altitude elevations, although their presence is also relevant around El Batán deposit (in Las Parras del Río Martín) during the Early Holocene. The transition towards the Late Holocene is evidenced by the rise of nitrophilous and ruderal taxa, which are linked to the spread of agricultural and grazing practices along the river valleys.
