“…Isotopic compositions are expressed as δ 13 C and δ 18 O in ‰ relative to V-PDB, with a precision better than ± 0.1‰ (based on replicate analyses of samples and standards). Stable hydrogen and oxygen isotope compositions were determined in the water extracted from fluid inclusions at the IGGR, Budapest, using the laser spectrometric method described by Czuppon et al (2014) and Demény et al (2016a). The reproducibilities of the δD and δ 18 O values are better than ± 2 and 0.5‰, respectively.…”

Highlights Stable isotope compositions of a last interglacial (LIG) stalagmite, Central Europe  A sequence of climate change events during the LIG for European speleothems  Hydrogen isotope data of inclusion water reveal a major event at about 125 ± 2 ka  Temperature and winter precipitation changes around the Mediterranean at 125 ± 2 ka ABSTRACT Studies on the last interglacial (LIG) can provide information on how our environment behaved in a period of slightly higher global temperatures at about 125 ± 4 ka, even if it is not the best analogue for the Holocene. The available LIG climate proxy records are usually better preserved and can be studied at a higher resolution than those of the preceding interglacials, allowing detailed comparisons. This paper presents complex stable hydrogen, carbon and oxygen isotope records obtained for carbonate (δ 13 Baradla data indicate enhanced aridity and seasonality for a part of GS26, with the relative dominance of summer precipitation and Mediterranean moisture contribution. Following the GS26 event, the effect of long-term global cooling becomes dominant in the Baradla isotope records and leads to glacial inception at about 109 ka.

“…Hydrogen isotope composition of fluid inclusion-hosted H 2 O in separated portions of vein-filling Cd-2 saddle dolomite (M-1/10/1 sample) was determined by vacuum crushing at the Institute for Geological and Geochemical Research of the Hungarian Academy of Sciences (Budapest) following the method described by Czuppon et al (2014) and Demény et al (2016). Separated chips of 2-3 g (3-5 mm in diameter) were placed in stainless steel tubes, pumped to vacuum, and then crushed using a hydraulic press.…”

“…13,14 When applied to vein-type deposits, fluid inclusion isotope data can be used to reconstruct basin-scale fluid flow circulation in the subsurface, which mainly finds an interest in ore geology, [15][16][17][18] petroleum geology, 19,20 and petrology. 21 Isotope analysis of fluid inclusions is not straightforward, as inclusions are only microns to hundreds of microns in size. As a consequence, bulk analytical techniques have mostly been developed, in which the integral volume of a large number of fluid inclusions within a mineral sample is released and subsequently analyzed.…”

“…Laser spectroscopy techniques developed for fluid inclusion isotope analysis use crusher units similar to IRMS setups and run on a dry nitrogen carrier gas, 10,39 on a "wet" carrier gas containing a constant standard water background, 40,41 or under vacuum. 21 For continuous-flow IRMS and CRDS setups, reported precisions for fluid inclusion δ 18 O analysis of mineral samples (δ 18 O fi values) are usually around 0.5‰, whereas precisions between 1.5‰ and 2‰ are reported for fluid inclusion δ 2 H analysis (δ 2 H fi values). Such precisions can be achieved for water yields as low as 0.15-0.2 μL.…”

Online oxygen (δ 18 O) and hydrogen (δ 2 H) isotope analysis of fluid inclusion water entrapped in minerals is widely applied in paleo-fluid studies. In the state of the art of fluid inclusion isotope research, however, there is a scarcity of reported inter-technique comparisons to account for possible analytical offsets.Along with improving analytical precisions and sample size limitations, interlaboratory comparisons can lead to a more robust application of fluid inclusion isotope records.Methods: Mineral samples-including speleothem, travertine, and vein materialwere analyzed on two newly setup systems for fluid inclusion isotope analysis to provide an inter-platform comparison. One setup uses a crusher unit connected online to a continuous-flow pyrolysis furnace and an isotope ratio mass spectrometry (IRMS) instrument. In the other setup, a crusher unit is lined up with a cavity ringdown spectroscopy (CRDS) system, and water samples are analyzed on a continuous standard water background to achieve precisions on water injections better than 0.1‰ for δ 18 O values and 0.4‰ for δ 2 H values for amounts down to 0.2 μL.Results: Fluid inclusion isotope analyses on the IRMS setup have an average 1σ reproducibility of 0.4‰ and 2.0‰ for δ 18 O and δ 2 H values, respectively. The CRDS setup has a better 1σ reproducibility (0.3‰ for δ 18 O values and 1.1‰ for δ 2 H values) and also a more rapid sample throughput (<30 min per sample). Fluid inclusion isotope analyses are reproducible at these uncertainties for water amounts down to 0.1 μL on both setups. Fluid inclusion isotope data show no systematic offsets between the setups. Conclusions:The close match in fluid inclusion isotope results between the two setups demonstrates the high accuracy of the presented continuous-flow techniques for fluid inclusion isotope analysis. Ideally, experiments such as the one presented in this study will lead to further interlaboratory comparison efforts and the selection of suitable reference materials for fluid inclusion isotopes studies.
