The Peña del Manto tufa is a cascade tufa located on left side of the Henar river, close to Deza village, Soria. This tufa has been studied combining the clasical methodologies, like sedimentological logging, and detail facies and geomorphological mapping, and additional techniques likes ERT, DGPS mapping, terrestrial LIDAR and 3D software modelling. Seven episodes have been identified based on the identification of major discontinuities or changes in the tufa system. These episodes record the evolution of the tufa system, in which carbonate production and clastic input stages alternates. Although there are no age data for this tufa, the Peña del Manto could have a similar age, middle Pleistocene, to those described in the same mountain range (i.e. Piedra and Mesa tufa systems). The alternation between carbonate production and clastic input episodes could reflect climatic changes, corresponding the first ones with interglacials and the sencond ones with glacial periods.
