Abstract Chlorine, lithium, and boron are trace elements in rhyolite but enriched groundwater flowing through because they tend to partition into the fluid phase during high‐temperature fluid‐rock reactions. We present a large data set of major element δ 37 Cl, 7 Li, 11 B compositions thermal water from Yellowstone Plateau Volcanic Field (YPVF). The Cl/B, Cl/Li, Cl (−0.2‰ +0.7‰), (−6.2‰ −5.9‰) values alkaline‐chloride waters reflect leaching chlorine, that has +0.1‰ +0.9‰ −6.3‰ −6.2‰,...
In order to trace the cycling of fluid-mobile elements (FMEs) through subduction zone forearcs, we collected water samples from two warm and 16 cold springs along subaerially exposed forearc Hikurangi in New Zealand. Water were analyzed for their cation anion concentrations, as well B, Li, Cl, O stable isotope compositions. Fluids discharging prism have high concentrations Cl (2400–16,000 mg/L), Br (6–70 I (0.4–72 Sr (0.1–200 B (3–130 Li (0.1–13 Na (33–6600 consistent with data previous...
Abstract Water controls magmatic crystallization and drives volcanic eruptions, but little is known about its primary source in silicic systems. The hydrogen isotope composition of products provides a metric that can track identify source, fractionation, or degassing processes. Despite such promise, measurements have never previously been acquired for undegassed melt. To explore whether isotopes the modification water magma reservoir, we analyzed D/H ratios dissolved H 2 O content...
The structural hydroxyl hydrogen (H)-isotope compositions of clay minerals are frequently used as tracers alteration or change in paleoenvironmental and material science studies. Dissolution pre-treatments commonly to remove cements H-bearing impurities prior isotopic analysis. These include reactions respectively with: HCl acetic-acetate buffer, H2O2 NaClO, a Na-dithionite-Na-citrate-bicarbonate (DCB) solution order carbonates, organic matter, iron (oxy)hydroxides. However, there has been...
