“…Geochemical modelling (Amiotte-Suchet and Probst, 1995;Gaillardet et al, 1997;Probst et al, 1997) and geochemical tracers (Négrel et al, 1993;Probst et al, 1994;Gaillardet et al, 1999;Mortatti and Probst, 2003) have been used to distinguish DIC originating from atmospheric/soil CO 2 and from carbonate dissolution. Nevertheless, each DIC source has a different υ 13 C isotopic signature ( 26 to 9‰ for soil organic matter according to whether C 3 or C 4 plants (Mariotti, 1991), 8 to 6‰ for atmospheric CO 2 (Cerling et al, 1991) and around 0‰ for carbonate rocks (Keith and Weber, 1964)), but few studies have been devoted to the use of carbon isotopes to trace the different DIC sources, to follow the riverine DIC transport into the ocean and to assess the carbon transformation in the river itself (Hitchon and Krouse, 1972;Dandurand et al, 1982;Kendall et al, 1992Kendall et al, , 1995Pawellek and Veizer, 1994;Cameron et al, 1995;Flintrop et al, 1996;Taylor and Fox, 1996;Yang et al, 1996;Amiotte-Suchet et al, 1999;Aucour et al, 1999;Barth and Veizer, 1999;Telmer and Veizer, 1999).…”

Abstract:The main Patagonian rivers (Colorado, Negro, Chubut, Deseado, Coyle, Chico, Santa Cruz and Gallegos) were sampled between September 1995 and November 1998 to determine their chemical and isotopic compositions, the origins of the suspended and dissolved river loads and their inputs to the South Atlantic Ocean. This paper focuses on the dissolved inorganic carbon (DIC) transport and its υ 13 C isotopic signature. The υ 13 C DIC values vary between 12Ð8 and 1Ð8‰ and allow one to distinguish two river groups: (i) the Colorado, Negro, Chubut and Santa Cruz, which display the highest values and the lowest seasonal variations; (ii) the Deseado, Coyle, Chico and Gallegos, which show the lowest values and the highest seasonal variations. For the first group, υ 13 C DIC is mainly controlled by important exchanges between the river waters and atmospheric CO 2 , due to the presence of lakes and dams. For the second group, υ 13 C DIC also appears to be controlled by the oxidation of organic carbon, showing a negative relationship between υ 13 C DIC and the dissolved organic carbon. These biogeochemical processes interfere with the contribution of carbonate and silicate weathering to the riverine DIC and do not allow use of υ 13 C DIC alone to distinguish these contributions. The annual DIC flux exported by Patagonian Rivers to the South Atlantic Ocean averages 621 ð 10 9 g. of C, i.e. a specific yield of 2Ð7 g m 2 year 1 . The mean υ 13 C DIC can be estimated to 4Ð9‰, which is high compared with other rivers of the world.

“…Radiocarbon studies of ground water have resulted in the formulation of different models which estimate initial 14C activity of HC03-ions dissolved in water (Pearson, 1965;Vogel, 1970;Mook, 1976Mook, , 1980Eichinger, 1983). However, physi-cochemical processes involved in precipitation of tufa are complex, and numerous environmental factors may influence them (Friedman, 1970;Usdowski, Hoefs & Menschel, 1979;Dandurand et al, 1982;Michaelis, Usdowski & Menschel, 1985; Thorpe, Otlet & Sweeting, 1980;Szulc, 1984). Direct application of such models in 14C dating of tufa has led to unsatisfactory results (Thorpe et al, 1981;Krajcar et al, 1985).…”

The Relations Between Carbon Isotope Composition and Apparent Age of Freshwater Tufaceous Sediments

ABSTRACT. This paper presents a synthetic approach to 14C dating of calcareous tufa, based on statistical analysis of correlations betwen lithologic type of tufaceous sediment, carbon isotope composition, and apparent age. Experimental data on several profiles from southern Poland and the United Kingdom reveal either constant or systematically changing values of apparent age. Constant value of apparent age in a profile can be attributed to calcareous muds precipitated from stagnant or low-energy water, and to tufas precipitated from turbulent water (oncoids, stromatolites, moss travertines) which are characterized by lack of significant correlation between 513C and 14C age of tufa carbonate. It was found that the relation between the apparent age of tufaceous sediment and 5'3C value of tufa carbonate depends on lithologic type of tufa. Phenomenological equations describing the dependence of apparent age upon S13C are given, and applied to estimate true ages of tufas from Gliczarow (southern Poland) and Folkestone (United Kingdom).

“…The general nature of the diurnal trends observed at Davys Creek is similar to that documented at other sites around the world (Barnes, 1965;Dandurand et al, 1982;Spiro and Pentecost, 1991;Pentecost, 1994): at-a-station minima in dissolved ions (measured as SC or dissolved CaCO 3 ) usually occur in the mid-afternoon when water temperature reaches its maximum and P CO 2 is closest to atmospheric levels, whereas maximum ion concentrations between sunrise and mid-morning coincide with minimum water temperatures and P CO 2 peaks.…”

Abstract:At-a-station diurnal variations in carbonate hydrochemistry were measured during four observation periods at Davys Creek, a tufa-depositing stream in central NSW, Australia. Major ion concentrations and continuously logged measurements of specific conductivity, pH and temperature showed that changes in the amount of CaCO 3 deposited upstream of the study reach were directly related to changes in diurnal water temperatures, which control the rate of CO 2 efflux to the atmosphere. The greatest upstream losses occurred during the mid-afternoon water temperature peak, whereas the lowest upstream losses occurred at sunrise, when water temperatures were at their lowest. Cloudy days at all times of the year produced small diurnal water temperatures ranges (c. 2-5°C) and, consequently, relatively small changes in upstream CaCO 3 loss (23-50 mg L 1 ) through the day. Clear sunny days, especially during summer months, produced large diurnal water temperature changes (up to c. 11°C), which in turn triggered diurnal changes in upstream CaCO 3 loss of up to 100 mg L 1 . By implication, the active reach of tufa deposition must advance downstream and increase in length during the evening and vice versa during the day. Given that the temperature of Davys Creek waters are a function of insolation, changes in the reach of tufa deposition under baseflow conditions are a direct function of the prevailing weather. This has implications for the palaeoclimatic interpretation of fossil tufa deposits.
