A comparison of isotope ratio mass spectrometry and cavity ring‐down spectroscopy techniques for isotope analysis of fluid inclusion water

“…[5][6][7][8][9][10][11][12] Fluid inclusion isotope data of halite deposits have been used to reconstruct the isotope history of ocean water. 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.…”

“…6,7,34 Furthermore, the technique has successfully been applied on hydrothermal vein mineralization to gain insight into subsurface fluid flow dynamics. [18][19][20]35 As a more cost-efficient alternative, fluid inclusion isotope ratios may also be measured on an IRMS instrument using an off-line extraction method. 36 Since the beginning of the 2010s, new online setups have been developed using cavity ring-down spectroscopy (CRDS), which was already an established technique for the accurate isotope analysis of water samples.…”

Regional-scale paleofluid system across the Tuscan Nappe–Umbria–Marche Apennine Ridge (northern Apennines) as revealed by mesostructural and isotopic analyses of stylolite–vein networks

“…In other cases, mineralization records an infill of meteoric fluids flowing downward or of hydrothermal fluids (i.e. hotter than the host rock they precipitated in) flowing upward, either from the basin or the basement rocks through large-scale faults or décollement (Roure et al, 2005;Vandeginste et al, 2012;Cruset et al, 2018;Lacroix et al, 2011;Travé et al, 2000Travé et al, , 2007De Graaf et al, 2019;Callot et al, 2010;Beaudoin et al, 2011Beaudoin et al, , 2014Bertotti et al, 2017;Gonzalez et al, 2013;Lucca et al, 2019;Mozafari et al, 2019;Storti et al, 2018;Vannucchi et al, 2010).…”

Fluid evolution and ore deposition in the Harz Mountains revisited: isotope and crush-leach analyses of fluid inclusions

“…For example, the release of structural-bound water in OH-groups by decrepitation at high temperatures is known to cause significant deviations in fluid inclusion isotope ratios for fluorite (Baatartsogt et al 2007b) and quartz (Grant et al 2003). The low-temperature crushing technique already has a record of producing reliable isotope data when applied to lowtemperature calcite veins (De Graaf et al 2017, 2019Bertotti et al 2017). Lüders et al (1993c), showing the distribution of the main Mesozoic ore deposits.…”
