Rudjer Bošković Institute radiocarbon measurements XVII

In this paper we present dating of geological (speleothems, tufa, soil and sediment), biological (molluscs and botanical), as well as hydrogeological samples from Croatia, Slovenia, Bosnia and Herzegovina, Turkey and China. Included are results of samples measured by GPC method till the abandonment of this technique in 2007, as well as results of several series measured by both GPC and LSC methods. In this report we present dating of different geological samples, mainly carbonate deposits as speleothems (submerged and terrestrial), tufa and lake sediments, as well as hydrological samples. We also present here some environmental samples such as plants, soil and shells. Samples were measured by gas proportional counter (GPC) prior to 2007 and since 2003 by liquid scintillation counter (LSC) technique using sample preparation in form of methane (Srdoč et al. 1971, 1979) and either benzene or direct absorption of CO2 (Horvatinčić et al. 2004), respectively. We use Oxalic Acid I and Oxalic Acid II as modern standards for GPC and LSC measurements, respectively.
