“…Noble gas concentrations in fluid inclusion water Underlying principle and assumptions. Noble gas temperature (NGT) determination is based on the fact that the equilibrium concentrations of dissolved atmospheric noble gases in water are a function of temperature, pressure, and salinity (e.g., Brennwald et al, 2013;Kipfer et al, 2002). Since the salinity of cave drip water is typically very low, and the pressure is given by the elevation of the sampling site (e.g.…”

“…Consequently they can be used to interpret the physical processes which are often poorly constrained by other, more reactive, tracers. For example noble gases have proven their potential in topics as diverse as understanding the source, migration and sinks of fluids throughout the crust (e.g., Ballentine et al, 2002; http Brennwald et al, 2013;Pinti et al, 2013) through to aiding our understanding of the origin and evolution of our planet (e.g., Holland et al, 2009;Marty, 2012;Halliday, 2013).…”

Quantifying the distribution of noble gases between phases is essential for using these inert trace gases to track the processes controlling multi-phase subsurface systems. Here we present experimental data that defines noble gas partitioning for two phase CO 2 -water systems. These are at the pressure and temperature range relevant for engineered systems used for anthropogenic carbon capture and geological storage (CCS) technologies, and CO 2 -rich natural gas reservoirs (CO 2 density range 169-656 kg/m 3 at 323-377 K and 89-134 bar). The new partitioning data are compared to predictions of noble gas partitioning determined in low-pressure, pure noble gas-water systems for all noble gases except neon and radon. At low CO 2 density there was no difference between measured noble gas partitioning and that predicted in pure noble gas-water systems. At high CO 2 density, however, partition coefficients express significant deviation from pure noble gas-water systems. At 656 kg/m 3 , these deviations are À35%, 74%, 113% and 319% for helium, argon, krypton and xenon, respectively. A second order polynomial fit to the data for each noble gas describes the deviation from the pure noble gas-water system as a function of CO 2 density. We argue that the difference between pure noble gas-water systems and the high density CO 2 -water system is due to an enhanced degree of molecular interactions occurring within the dense CO 2 phase due to the combined effect of inductive and dispersive forces acting on the noble gases. As the magnitude of these forces are related to the size and polarisability of each noble gas, xenon followed by krypton and argon become significantly more soluble within dense CO 2 . In the case of helium repulsive forces dominate and so it becomes less soluble as a function of CO 2 density.

[1] This paper presents a novel extraction device for water and noble gases from speleothem samples for noble gas paleotemperature determination. The ''combined vacuum crushing and sieving (CVCS) system'' was designed to reduce the atmospheric noble gas contents from air inclusions in speleothem samples by up to 2 orders of magnitude without adsorbing atmospheric noble gases onto the freshly produced grain surfaces, a process that had often hampered noble gas temperature (NGT) determination in the past. We also present the results from first performance tests of the CVCS system processing stalagmite samples grown at a known temperature. This temperature is reliably reproduced by the NGTs derived from Ar, Kr, and Xe extracted from the samples. The CVCS system is, therefore, suitable for routine determinations of accurate NGTs. In combination with stalagmite dating, these NGTs will allow reconstructing past regional
