“…The calculated water composition ranged from -12.7 to -8.0‰ (Fig. 7), in good agreement with published values (from -14 to -8‰; Varsányi et al 2011). For precipitation water there is a well-known relationship between the water's oxygen isotope composition and the ambient temperature that depends on the local climate conditions.…”

“…The temperature change related to the PleistoceneHolocene transition was at least 4.9°C in terms of global mean, whereas the rise in annual mean temperature within the Carpathian Basin reached about 8-10°C on the basis of malacothermometry (Sümegi and Krolopp 2002), noble gas thermometric groundwater analyses (Varsányi et al 2011) and stable oxygen isotope compositions of fossil teeth (Kovács et al 2012). Using fossil chironomid species analyses on lake sediments from the Southern Carpathians, Tóth et al…”

In this paper we present sedimentological and geochemical data for a section of fluvial deposits from SE Hungary covering the period from about 20 to 5 ky BP. Major and trace element geochemistry of bulk sediments as well as stable C and O isotope compositions of the carbonate content indicate significant changes in depositional facies and/or sediment provenance as well as climate conditions. Variations in bulk sediment Sr, TiO 2 and P 2 O 5 concentrations were correlated with major climate change events following the Late Glacial Maximum that support the age model established on the basis of AMS 14 C age data. Bulk sediment Sr concentrations and stable C and O isotope compositions of bulk sediment carbonate were determined by changes in denudation of carbonate rocks in the recharge area. The Sr and C-O isotope patterns show correlations with global temperature changes during the Pleistocene-Holocene transition. However, TiO 2 and P 2 O 5 contents show correspondence with humidity changes, suggesting variations in chemical weathering. In addition to the sedimentological effects, C and O isotope compositions of Unio crassus shell fragments show strong changes at the Pleistocene-Holocene transition, indicating that the bivalve shells can reflect climate conditions. On the other hand, shorter climate change events were difficult to track in the isotope records due to the competing fractionation processes. The combined evaluation of chemical and isotopic compositions revealed that beside the globally important Younger Dryas and Bølling/Allerød periods, the Ságvár-Lascaux interstadial was of local importance, in accordance with earlier studies.

“…14 C is the most widely used radiogenic dating technique in regional aquifers because of the ubiquitous presence of dissolved inorganic carbon (DIC) in groundwater and the potential to date up to 50000 years old samples. Recent palaeo-climate studies, where isotopic ratios of noble gases show the environmental temperature change during the past, also need precise groundwater dating technique which are currently mostly based on C-14 analyses [5,6].…”
