  • Radiocarbon Dating of the Zagreb Upper Town Prehistoric Settlement

    Open Access•Bogomil Obelić, Marija Šmalcelj et al.•ARTICLE•Radiocarbon•1995•Citada por: 1•Referencias: 10

    During the 1989–1994 renovation of the Zagreb Town Museum, it became obvious that the area was inhabited in prehistoric times. We 14 C dated 40 samples to determine various settlement periods. The ages of the samples span a much longer time than expected, from the Early Iron Age (Hallstatt period) to the 19th century ad. 14 C dates on charcoal samples placed the remains of dwelling pits in the Hallstatt period, 8th to 4th century bc. A late La Tè…

    In this list, we present 14 C ages of archaeological, geological, hydrogeological, botanical and atmospheric samples measured since our previous list (Srdoč et al. 1992). Chemical pretreatment and counting techniques using a methane-filled proportional counter are essentially the same as reported earlier. Sample descriptions are prepared in collaboration with collectors and submitters

    We present here radiocarbon analyses made since our previous list (Srdoč et al. 1989). Sample pretreatment, combustion and counting techniques are essentially the same as described previously (Srdoč, Breyer & Sliepčević 1971), supplemented by new techniques for groundwater processing (Srdoč et al. 1979). The calculation of ages follows conventional protocol (Stuiver & Polach 1977). These ages can be converted from the 5570-year half-life to the c…

    The following radiocarbon date list contains dates of samples from Plitvice Lakes measured since our previous list dealing with tufa from this region (Srdoč et al , 1982). Tufa measurements from the Knin area in S Croatia and some localities in Bosnia are also listed. Age calculations are based on the Libby half-life (5570 ± 30) yr and reported in years before 1950. Reported ages are based on the initial activity of 85% except for lake sediments …

  • Radiocarbon Dating of Lake Sediment from Two Karst Lakes in Yugoslavia

    Open Access•Dušan Srdoč, Bogomil Obelić et al.•ARTICLE•Radiocarbon•1986•Citada por: 10•Referencias: 2

    Samples of sediment cores from two lakes in the karst area of northwest Yugoslavia were analyzed. Both Lakes Kozjak and Prošće are in the Plitvice National Park, Central Croatia. 14 C dating, sedimentologic, seismic, and isotopic studies, and distribution of diatoms are presented. 14 C dating of lake marl revealed a uniforn sedimentation rate in Lake Prošće as opposed to Lake Kozjak. Both lake sediments belong to the Holocene period. 14 C dating …

  • Radiocarbon Dating of Tufa in Paleoclimatic Studies

    Open Access•Dušan Srdoč, Nada Horvatinčić et al.•ARTICLE•Radiocarbon•1983•Citada por: 6•Referencias: 2

    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 extensive and systematic radiocarbon dating of tufa samples and associated materials (wood, plants, moss, and peat) are presented in this paper. Samples were collected in Plitvice Lakes National Park, Central Croatia, Yugoslavia, where intensive precipitation of tufa has taken place over several geologic epochs in a typical Karst area. Problems associated with radiocarbon dating of tufa are discussed in a previous paper (Srdoč et al , …

    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.

    A systematic crosschecking of the NBS oxalic acid standard, the ANU Sucrose secondary standard, and the RB oak tree rings grown in 1858 ± 5 and 1890 ± 5 has been performed using the proportional counter technique. Details on the counter gas (methane) purification are given. Corrections of count rates due to changes of barometric pressure and ambient temperature are applied and discussed. Results of measurements are presented and the ratios betwee…

    The following radiocarbon date list contains dates of samples measured since our previous list (R, 1979, v 21, p 131-137). As before, age calculations are based on the Libby half-life 5570 ± 30 yr and reported in years before 1950. The modern standard is 0.95 of the activity of NBS oxalic acid. Sample pretreatment, combustion, and counting technique are essentially the same as described in R, 1971, v 13, p 135-140, supplemented by new techniques …

    Results of extensive and systematic radiocarbon dating of tufa samples and associated materials (wood, plants, moss, and peat) are presented in this paper. Samples were collected in Plitvice Lakes National Park, Central Croatia, Yugoslavia, where intensive precipitation of tufa has taken place over several geologic epochs in a typical Karst area. Problems associated with radiocarbon dating of tufa are discussed in a previous paper (Srdoč et al , …

  • Radiocarbon Dating of Tufa in Paleoclimatic Studies

    Open Access•Dušan Srdoč, Nada Horvatinčić et al.•ARTICLE•Radiocarbon•1983•Citada por: 6•Referencias: 2

    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…

    Samples of sediment cores from two lakes in the karst area of northwest Yugoslavia were analyzed. Both Lakes Kozjak and Prošće are in the Plitvice National Park, Central Croatia. 14 C dating, sedimentologic, seismic, and isotopic studies, and distribution of diatoms are presented. 14 C dating of lake marl revealed a uniforn sedimentation rate in Lake Prošće as opposed to Lake Kozjak. Both lake sediments belong to the Holocene period. 14 C dating …

    The following radiocarbon date list contains dates of samples from Plitvice Lakes measured since our previous list dealing with tufa from this region (Srdoč et al , 1982). Tufa measurements from the Knin area in S Croatia and some localities in Bosnia are also listed. Age calculations are based on the Libby half-life (5570 ± 30) yr and reported in years before 1950. Reported ages are based on the initial activity of 85% except for lake sediments …

    During the 1989–1994 renovation of the Zagreb Town Museum, it became obvious that the area was inhabited in prehistoric times. We 14 C dated 40 samples to determine various settlement periods. The ages of the samples span a much longer time than expected, from the Early Iron Age (Hallstatt period) to the 19th century ad. 14 C dates on charcoal samples placed the remains of dwelling pits in the Hallstatt period, 8th to 4th century bc.
