“…Indeed, early research undertaken by Pazdur et al (1988) concluded that the oxygen isotope composition of fossil Polish tufa appeared to be sensitive to temperature and humidity, in reasonable agreement with other temperature proxies for southern Poland. Subsequent research by Andrews et al (1993Andrews et al ( , 1997Andrews et al ( , 2000, Janssen (2000), Matsuoka et al (2001) and Ihlenfeld et al (2003) concluded that the isotope geochemistry of recent tufa contains an interpretable palaeoclimatic and palaeoenvironmental signal; a signal that may also be preserved in fossil tufa (Andrews et al, 1994).…”

Combined stable isotope (d18O and d13C) and trace element (Mg, Sr) geochemistry from bulk tufa calcite and ostracod shell calcite from an early Holocene British tufa reveal clear records of Holocene palaeoclimatic change. Variation in d18O is caused principally by change in the isotopic composition of Holocene rainfall (recharge), itself caused mainly by change in air temperature. The d13C variability through much of the deposit reflects increasing influence of soil-zone CO2, owing to progressive woodland soil development. Bulk tufa Mg/Ca and Sr/Ca are controlled by their concentrations in the spring water. Importantly, Mg/Ca ratios are not related to d18O values and thus show no temperature dependence. First-order sympathetic relationships between d13C values and Mg/Ca and Sr/Ca are controlled by aquifer processes (residence times, CO2 degassing and calcite dissolution/reprecipitation) and probably record intensity of palaeorainfall (recharge) effects. Stable isotope records from ostracod shells show evidence of vital effects relative to bulk tufa data. The ostracod isotopic records are markedly ‘spiky’ because the ostracods record ‘snapshots’ of relatively short duration (years), whereas the bulk tufa samples record averages of longer time periods, probably decades. The d18O record appears to show early Holocene warming, a thermal maximum at ca. 8900?cal. yr?BP and the global 8200?yr BP cold event. Combined d13C, Mg/Ca and Sr/Ca data suggest that early Holocene warming was accompanied by decreasing rainfall intensity. The Mg/Ca data suggest that the 8200?yr BP cold event was also dry. Warmer and wetter conditions were re-established after the 8200?yr BP cold event until the top of the preserved tufa sequence at ca. 7100?cal. yr BP

“…On the sub-annual time-scales of interest here, the relative effects of seasonal soil-air contribution (Hori et al 2008), CO 2 degassing and upstream/in-aquifer calcite precipitation (Ihlenfeld et al, 2003) are probably the most important contributors to the variability in δ 13 C. In a modern Japanese tufa system Matsuoka et al (2001) showed strong δ 13 C covariation between calcite and dissolved inorganic carbon δ 13 C (δ 13 C DIC ). They demonstrated that δ 13 C DIC is dependent on degassing/calcite precipitation (prior calcite precipitation -PCP) processes in the aquifer.…”

Early papers concentrated on environmentally well-characterised recent and sub-recent deposits (Matsuoka et al 2001;Kano et al, 2003) that established the potential for recovery of seasonal palaeoclimatic records.…”

Recent and sub-recent laminated tufa stromatolites can contain high resolution δ 18 O records of in stream temperature change. Fossil tufa stromatolites are therefore key targets for reconstructing terrestrial palaeoclimatic, but so far only a few examples have been published.In this research we studied a 2.5 cm-radius tufa stromatolite from the Eemian of the Somme Basin, Northern France. We show; (1) that high resolution sampling of fossil laminated tufas is highly reproducible. We demonstrate; (2) that within the limitations of the δ 18 O method, NW European Eemian seasonality was essentially similar to the present day. Perhaps most important we show; (3) that precise observations from thin section that match the position of 1 Present address: GéoArchÉon, 30 rue de la Victoire, 55210 Viéville-sous-les-Côtes, France A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT

“…According to equation (1), the chemistry of most tufas and travertines is dominated by calcium carbonate, although a range of minor minerals is almost always present. For example, Ihlenfeld et al (2003) found, in a detailed study of tufa geochemistry on samples from Gregory River, northern Queensland, Australia, that calcite formed around 99.2% of the tufa by weight, with quartz (c. 0.25 wt%), kaolinite (c. 0.35 wt%) and nontronite-rich smectite (c. 0.2 wt%). Silica can sometimes be present in the amorphous state (e.g.…”

“…Tufas also tend to be precipitated at more rapid rates than speleothems and deposited in a less regular manner. Trace element ratios within tufas and travertines, such as Mg/Ca and Sr/Ba, can also be used to reconstruct palaeoclimatic and palaeoenvironmental conditions (Ihlenfeld et al, 2003), although their interpretation is often complex and requires an understanding of whether the tufas and travertines were precipitated in equilibrium with the surrounding waters.…”
