One of the most common methods for estimating paleohydrothermal δ D values in epithermal quartz veins is hydrogen isotope analysis of H 2 O extracted from fluid inclusions in quartz by thermal decrepitation. The validity of the method is questioned. The δ D values of water extracted from fluid inclusions in clear euhedral quartz from active geothermal systems are up to 30 per mil more negative than the δ D value (–42‰) of the geothermal water. Measured δ D values of the fluid inclusion water are dependent on the temperature at which the water in the quartz was extracted. Water extracted at 800°C has δ D values about 10 to15 per mil lower than fluid inclusion water extracted at 500°C (–53 to –61‰). Fluid inclusion water in calcite from an active geothermal well has δ D values that match those of the geothermal water. Calcite is thus potentially a more suitable mineral for estimating paleohydrothermal δ D values.

The soil component of atmospheric CO2 oxygen isotope budget is evaluated in light of the recent recognition of abiotic oxygen isotope exchange of atmospheric CO2 and soil water in excess of soil respiratory CO2 flux. By using variations of published analytical models, we estimate that the amount of atmospheric CO2 that undergoes oxygen isotope exchange with soil water, exclusive of soil‐respired CO2, to be approximately 0.2–0.7 μmol m−2 s−1 for representative unsaturated soils from a range of biomes. Globally, the amount of atmospheric CO2 that undergoes oxygen isotope exchange with soil water through purely nonbiological processes is probably significantly larger than the current annual fossil fuel combustion, yet this process has been neglected in all recent global 18O‐CO2 budgets. Furthermore, abiotic oxygen isotope exchange with soils will occur roughly equally in soils with low and high respiration rates, suggesting that soils with low respiration rates are currently under‐represented disproportionately in the existing global CO2 oxygen isotope budgets. Because soils with low respiration rates tend to have the most extreme soil water δ 18O values, their underrepresentation may have a large and heretofore unsuspected impact on the global atmospheric C18 O16O budget. Finally, soil carbon is no longer in steady state due to land use practices, and this additional source of CO2 to the atmosphere may contribute to the decreasing trend in atmospheric CO2‐δ18O values through time.
