Resumen

Fluvial tufa build-ups located in the Val river (Ágreda, Soria province) have been investigated. Important tufa terraces crop out from Val spring to 8 km downstream along the river. U/Th ages derived from post-depositional speleothems corroborate previous radiocarbon ages stablished along the Holocene. In a higher position respect to the river an extensive terrace dominates the landscape in the area. These tufa buildings show stem rudstonse, floatstones and packstones, leaf prints and eventually oncoid-rich facies. U/Th ages mark a period of tufa development around 240 ky ago, corresponding with the increase of water availability during MIS7. Similar tufa growing periods are recognized in other rivers through the Iberian Range.
