Tengchong geothermal field; the exact spring is not named. Silicon gets heavier from vein quartz (first precipitated) to sinter to water, as expected from kinetic precipitation fractionation. Coordinates of Tengchong town, indicative.

| 0.3 ‰ | 0 / 0.7 ‰ | 4 | thermal water Spring water: 0.0 to 0.7 ‰, mean 0.3 ‰ (n = 4) per the text; Table 2 prints -0.3 ‰, inconsistent with the range. | Li et al. (1995), Experimental study of silicon isotope dynamic fractionation and its app… |
| −0.1 ‰ | −0.6 / 0.2 ‰ | 7 | siliceous sinter Siliceous sinter at the vent: -0.6 to +0.2 ‰ (Table 2), mean -0.1 ‰ (n = 7). The text gives -0.6 to -0.2 ‰, inconsistent with the mean. | Li et al. (1995), Experimental study of silicon isotope dynamic fractionation and its app… |
