Yellowstone National Park. Sodium chloride spring with 470 ppm SiO2, pH 7.8-8.1, supersaturated in amorphous silica; samples from the pool (81.8 °C) to 20 m downflow (33.5 °C). Cooling drives precipitation.

| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 0.37 ± 0.23 ‰ | 0.15 / 0.7 ‰ | 5 | thermal water (dissolved silicon) Mean and standard deviation recalculated from 5 samples. CS1 to CS5: water gets heavier downflow as light sinter precipitates. Pool consistent with 0.1 ‰ (Douthitt, 1982). | Chen et al. (2020), Silicon isotope variations in hydrothermal systems at Yellowstone Nat… |
| −3.74 ± 1.38 ‰ | −5.04 / −2.25 ‰ | 5 | siliceous sinter (opal-A) Mean and standard deviation recalculated from 5 samples. CS1 to CS5: sinter increasingly light downflow; Δ30Si(sinter-water) -2.40 to -5.57 ‰, kinetic fractionation. | Chen et al.
