  • Radiocarbon and Uranium-Series Dating of the Plitvice Lakes Travertines

    Open Access•Dušan Srdoč, J K Osmond et al.•ARTICLE•Radiocarbon•1994•Cited by: 4•References: 51

    Radiocarbon and uranium-series ages of the calcareous deposits of the Plitvice Lakes show that travertines were deposited during three warm, humid, interglacial oxygen isotope stages. According to our measurements, only calcite crystals or crystal aggregates represent reliable material for both 230 Th/ 234 U and 234 U/ 238 /U dating. Compact old travertine in the form of sandstone is less reliable; it can be dated by both methods provided that it…

    Two principal reasons for the inherent uncertainty in 14 C dating of calcareous sediments such as tufa or those of lacustrine origin are the unknown initial 14 C activity (A o ) of the sediment, mainly affecting younger (Holocene) samples, and contamination of older sediments with recent carbonate, causing 14 C ages to be excessively young. To assess the contamination effect, samples of old tufa from the Riss/Würm interglacial were examined. Thes…

    Open Access•Dušan Srdoč, Bogomil Obelić et al.•ARTICLE•Radiocarbon•1980•Cited by: 9•References: 1

    Systematic dating of tufa samples has been undertaken to establish a chronology of tufa deposits in Plitvice National Park, Yugoslavia. We conclude that tufa samples give reproducible data within the time span of ≈ 40,000 years up to recent. The 14 C/ 12 C ratio of carbon in the ambient biosphere and hydrosphere gives a detailed picture of the distribution of carbon isotopes in the investigated system. Despite the susceptibility of calcareous mat…

    Calcareous deposits known as tufa or travertine contain biogenic carbon and are a potential source of geochronologic information. Many dated samples from Karstic regions in Yugoslavia proved that 14 C analyses of tufa can provide reliable data reflecting climatic conditions in the past. Systematic dating of tufa samples revealed two distinct groups of deposits: recent tufa deposits, with a sharp age limit of ∼6000 ± 500 years BP, and old tufa dep…

    Results of measurements for 3 years (1981–1983) of 14 C activity of dissolved inorganic carbon (DIG) in water samples from the Korana River, as well as that of recent tufa and aquatic plants, showed that 14 C concentration increases from karst spring to the estuary. A model describing the increase of 14 C activity was developed assuming that the increase is due to the exchange of the dissolved CO 2 in stream water with atmospheric CO 2 and to dis…

  • The Effects of Contamination of Calcareous Sediments on their Radiocarbon Ages

    Open Access•Dušan Srdoč, Nada Horvatinčić et al.•ARTICLE•Radiocarbon•1986•Cited by: 5•References: 5

    Two principal reasons for the inherent uncertainty in 14 C dating of calcareous sediments such as tufa or those of lacustrine origin are the unknown initial 14 C activity (A o ) of the sediment, mainly affecting younger (Holocene) samples, and contamination of older sediments with recent carbonate, causing 14 C ages to be excessively young. To assess the contamination effect, samples of old tufa from the Riss/Würm interglacial were examined. Thes…

    Open Access•Ines Krajcar Bronić, Nada Horvatinčić et al.•ARTICLE•Radiocarbon•1992•Cited by: 8•References: 18

    We have reconstructed the initial activity of calcareous sediments by 1) measuring the 14 C activity of recent pre-bomb-test calcareous deposits, 2) calculating the ratio of the 14 C activity of the calcareous sediment to that of the adjacent coeval wood, and 3) extrapolating 14 C activity of the deep lacustrine sediment layers to the surface, assuming a constant sedimentation rate. We show here that the uppermost sediment is affected by the glob…

    Anthropogenic activities that introduce an excess of nutrients and other pollutants into rivers and lakes are causing significant changes in their aquatic environment. Excessive nutrients greatly accelerate eutrophication, and lake marl formed during eutrophication differs from that formed in oligotrophic water. We analyzed recent sediment cores from Prošće and Kozjak lakes located in Plitvice National Park, central Croatia. Analyses consisted of…
