Development of Quaternary fluvial tufa buildings are often associated with warm and humid phases and are commonly used as climate indicators. El Nogal de El Batán Holocene fluvial tufa buildup, located in Las Parras River valley (Iberian Range, NE Spain), is investigated, following radiocarbon dating, stratigraphic description and palynological analysis. The studied deposit, 8.2 m-thick, is formed of gravels, phytoclast rudstones, calcite- coated stem boundstones and fine carbonate deposits (sands, silts and marls) with peaty horizons and carbonaceous debris. It has been dated within the upper early Holocene (ca. 8400 cal BP) and correlated with the environmental changes reconstructed for the region, identifying at least, three main phases. Pollen results highlight the existence of a conifer landscape, mainy dominated by Pinus nigra/sylvestris type and Juniperus, and locally dense riparian woodland with Corylus, Alnus, Salix, Populus, Celtis, Fraxinus, Tamarix and Rosaceae. Deciduous and evergreen oaks were the main spread regional forests accompanied by many warm-loving taxa like Pistacia, Rhamnus, Arbutus and Olea during the middle Holocene (ca. 8000-5000 cal BP). The transition towards the late Holocene (ca. 4300 cal BP) is evidenced by the rise of herbs and ruderal taxa, and especially the presence of coprophilous fungi, which are linked to the spread of agricultural and grazing practices along the river valley.
