“…To our knowledge, the only modern spring mounds that have received the kind of treatment that allows direct comparison of facies are those in the Great Artesian Basin (Keppel et al 2011; see section on Petrography and Facies). Most studies have focused solely on the chemistry of the carbonate, particularly as it relates to the chemistry of the waters that flow from the springs and to alteration by human activity (e.g., Mudd 2000;Fensham and Fairfax 2003;Valero Garcés et al 2008;Swanson et al 2014;Dabkowski et al 2015a).…”

Carbonate deposits in the Jurassic Navajo Sandstone of Utah reflect deposition in interdune lakes and springs. Interdune-lake deposits consist of flat-lying carbonate units. Springs formed tufa mounds that are interpreted as subaerial, ambient-temperature, artesian-spring deposits. In the first systematic study of the petrography of the carbonate deposits in the Navajo Sandstone, eleven facies were identified in several flat-lying carbonate deposits and two tufa mounds. Fenestral mudstone and peloidal facies dominate the lacustrine deposits, whereas thrombolitic mudstone characterizes the mounds. The biota consists of ostracodes, charophytes, fish, mollusks, a possible freshwater sponge, trace fossils, and fragments of vascular plants. Features resulting from penecontemporaneous weathering provide evidence of episodic exposure of the lacustrine carbonate beds during deposition and formation of the tufa mounds under subaerial conditions. Although carbonate deposits are not rare in eolian systems, few have been studied in detail; comparisons between these and the Navajo Sandstone carbonate deposits reveal some characteristics that may be unique to the latter.

“…More commonly, dated tufa sites provide 1 to 10 dates (4.7 dates in average; Fig. 1) rarely more, except at recently studied sites (Dabkowski et al, 2015;H ajek et al, 2016;Pazdur et al, 2002): in the last decades, high-quality radiometric dating became mandatory for publication in international journals while technical and methodological progress allowed to date new and smaller amount of material.…”

“…Baker and Simms (1998) thus demonstrated that 'there has been a considerable underreporting of active tufa deposition' and that 'this observation, in turn, suggests that the same has occurred for fossil sites'. In the last decades, the growing development of investigations on calcareous tufas in Europe and considerable improvements in dating methods, especially radiocarbon dating, have provided reliable evidence of deposits developing until our present days (Andrews et al, 2000;Dabkowski et al, 2015;Dobrowolski et al, 2002Dobrowolski et al, , 2005H ajek et al, 2016;Lo zek, 2009;Pedley et al, 1996;Srdo c et al, 1980). All these publications also illustrate a large diversity in tufa deposits.…”

In 1993, Goudie and co-authors named the postulate that there would be a marked decline in the deposition of calcareous tufa in Europe since ca. 2500 BP 'the late-Holocene tufa decline'. However, the growing development of investigation on calcareous tufas and considerable improvement in dating methods, especially radiocarbon dating, has provided reliable evidence of deposits developing until our present days. I thus discuss the reality of the decline, reviewing 62 tufa sites in Europe and their time distribution based both on radiocarbon dates and biochronological data and distinguishing different cases depending on tufa size and types. I demonstrate that the late-Holocene tufa decline is actually a general view of a rather complex tendency: after a maximum during the Atlantic period, fluvial tufas are systematically affected by a decline from ca. 5 ka cal. BP but no general trend is shown in the development of proximal (spring-fed) or lacustrine tufas. This observation is likely to result from the increasing impact of human activity (mainly deforestation) on landscapes, and more specifically on fluvial environments, from the Bronze Age.

“…Their mineralogy (typically >95 % CaCO 3 ) makes them highly suitable archives of stable isotope (d 18 O and d 13 C) and trace element (Mg, Ca) information, from which palaeoclimatic conditions can be inferred (Dabkowski, 2014). Recently, scientific interest in Pleistocene tufas as palaeoclimatic archives has increased (Martín-Algarra et al, 2003;Antoine et al, 2006;Limondin-Lozouet et al 2006;Preece et al, 2007;Ashton et al, 2008 ;Ortiz et al, 2009;Domínguez-Villar et al, 2011) but to date, most of the geochemical work on tufas has been on recent and Holocene aged material (see review by Andrews & Brasier, 2005;Andrews, 2006;Dabkowski et al, 2015), with just a small number of studies focused on older material (Brasier et al, 2010;Dabkowski et al, 2011Dabkowski et al, , 2012.…”

The geochemical content of calcareous tufa has been recently proven to provide reliable reconstructions of climate variability during Pleistocene interglacials. As one of the best documented, the Last Interglacial (also known as the Eemian in continental area or the MIS 5e in marine records) has been frequently referred to as an analogue for the Holocene. The Caours tufa deposit from northern France provides a long record of the evolution of both climate and environment during the Last Interglacial. Geochemical data in tufa calcite are interpreted to record primarily air temperature (d 18 O), biomass productivity (enhanced during wetter-warmer-periods; d 13 C) and rainfall intensity (Mg/Ca). The combined data identify a warm and wet climatic optimum followed by oscillations of temperature and humidity conditions. These climatic variations recorded through the Caours profile are strongly consistent with the palaeoenvironmental reconstructions from malacological data. Comparison with those derived from a Grande Pile pollen record suggests that tufa may have precipitated at Caours from ca. 126 to ca. 115 ka (i.e. during the MIS 5e) and that the recorded climatic variations could be related to significant events affecting the Northern Atlantic region. Data comparison with the isotopic record from a speleothem (BDinf) from Bourgeois-Delaunay cave, in southwestern France, confirms the relative climatic instability recorded during the Last Interglacial at Caours.
