“…In the last decade, scientific interest in tufas as palaeoenvironmental and palaeoclimatic archives has increased (e.g. Antoine et al, 2007; Dabkowski, 2014; Domínguez-Villar et al, 2011; González-Amuchastegui and Serrano, 2015; Ortiz et al, 2009; Pazzaglia et al, 2013; Ricci et al, 2015). As they mainly comprise of calcite (typically >95% CaCO 3 ) precipitating at an ambient temperature under open-air conditions (in streams, rivers and lake shorelines; Capezzuoli et al, 2014), tufas are suitable archives of geochemical information from which palaeoclimatic conditions can be inferred (Andrews, 2006).…”

Calcareous tufas are great archives of geochemical information for the reconstruction of past climate. Their importance increases in the regions where other proxies are rare, such as Western Carpathians. Here, we present the first whole-Holocene palaeoclimatic reconstruction for this region based on geochemical proxies. We analysed δ18O, δ13C and Mg/Ca ratio on tufa calcite of the Mituchovci site (White Carpathian Mountains, W Slovakia) and compared these with pollen, plant macrofossil and mollusc data. According to δ18O, two distinct thermal maxima occurred in the region, around 11.4 ka and between 7.3 and 6.9 ka BP. According to δ13C and Mg/Ca ratio, a steep increase in moisture and rainfall took place around 8.5 ka cal. BP, preceded by a cold and dry event. These events are well reflected in the biotic proxies and are suggested also by other palaeoenvironmental studies from the Carpathians. We found some later fluctuations, with dry and warm Bronze Age (ca. 3.6 ka cal. BP), cold and wet Urnfield period (ca. 2.8 ka cal. BP), warm Roman period (ca. 2 ka cal. BP) and cold but humid Migration period (ca. 1.5 ka cal. BP). We observed extreme abruptness and amplitude of the variation in all geochemical proxies in the last 500 years, when biotic proxies imply a very intense human deforestation. Land-use changes may have altered both the temperature regime in the studied fen and the carbon cycle in the recharge area.

“…In soil micromorphology studies, the entity of the processes identified hinders their correlation with the rapid climate change in the last Glacial Period (Areso, 1984; Hoyos and Fumanal, 1985; Areso and others, 1990; Pérez-Fernández, 2017, 2021). Cryoturbation processes and the growth of tufaceous structures in many parts of the Cantabrian region confirm the degree of humidity and milder temperatures, especially in the late glacial interstadial (González-Sampériz and others, 2006; González-Amuchástegui and Serrano-Cañadas 2015; Moreno and others, 2010; Aranbarri and others, 2014). The high humidity would explain the accumulation of carbonate by solution and, consequently, the loss of the original organic materials (Pérez-Fernández, 2021).…”

Upper Palaeolithic archaeological sites in the Basque Country have been excavated for over a century. They have yielded a rich palaeoenvironmental record with zoological and botanical remains that have been obtained in stratigraphic series dated precisely by radiocarbon. This information reveals cyclical environmental changes from climates similar to today to drier and extremely cold conditions, when species in current boreal biomes and others now extinct but with similar ecological preferences were present in the region. Moreover, the archaeological sites have provided high-resolution information about the resilience mechanisms of the communities of our own human species. This information allows us to increase the corpus of palaeoclimate data regarding the Marine Isotopic Stage (MIS) 2 and MIS 3 for a critical region within the human population of Eurasia. The aim of this paper is to show how an extraordinary capacity for adaptation to drastic climate changes Upper Palaeolithic hunter–gatherer societies displayed, even though their subsistence depended on biotic resources that alter rapidly.

“…Upstream from the tufa barriers, the waters of the river have been partially retained leading to a considerable calcarenitic infill in these areas; this infill is a carbonated deposit resulting from the destruction of tufa buildups situated higher up, and it reaches very sizable thicknesses. In the valley of the Purón, a single generation of tufa deposits from the Holocene has been detected [8], supported in some stretches of the valley by stratified deposits associated with the last episode of intense cold in the recent Pleistocene. These deposits have undergone a deep incision, although there are active processes of tufa precipitation in the valley (Figure 3).…”

“…In this structural context, the fluvial network has been the main morphogenetic agent [6,8], with fluvial forms corresponding to a long environmental evolution alternating between phases of accumulation and erosion. The Purón River, a tributary of the Ebro River, runs through the park inciding on the Turonian marls of the anticlinal nucleus to zig-zag across its southern flank such that it adapts to the different types of materials it encounters.…”

This study supports the usefulness of geomorphological mapping as a tool for gaining an understanding of the landscape and assessing natural heritage. Mapping provides an essentially scientific document with great potential for the diffusion of geomorphological knowledge in that it provides a guide to the user of natural protected areas as well as serving as a tool for its management regarding geotourist itineraries, geodiversity, and geomorphosites. The example of the Valderejo Natural Park is presented, which is located in Álava (Spain) and whose geomorphology has been mapped following a methodology based on fieldwork, desktop work, and the use of Geographic Information Systems. The map's applications are presented in the areas of tourism, geotourist maps, and for the assessment of natural heritage, geodiversity, and geomorphosites.
