Abstract

Thermodynamic oxygen isotope factors for wolframite are calculated using the modified increment method and assuming a predominant contribution of the 18 O-increment in complex anion to the I- 18 O index of complex mineral. The oxygen isotope fractionation factors obtained between quartz, wolframite and water are : 10 3 ln α quartz-wolframite =0.38×10 6 /T 2 +4.76×10 3 /T-2.48, 10 3 ln α wolfr a mite-water =3.86×10 6 /T 2 -8.54×10 3 /T + 1.44 for the temperature range from 0 to 1200°C. No difference in fractionation between ferberite and huebnerite is observed, indicating that the substitution of Fe for Mn does not significantly affect the 18 O/ 16 O partitioning in the wolframite series. When the present calibration for the quartz-wolframite system is applied to isotopic geothermometry in hydrothermal tungsten mineralizations, the temperatures calculated are well comparable to results from other geothermometric methods

  • Oxygen isotope inheritance in mineral formation by cation substitution has been supposed for the replacement of wolframite to scheelite in nature and apatite to BiPO4 in laboratory.

    “The oxygen isotope inheritance in mineral formation by cation substitution has been supposed for the replacement of wolframite to scheelite in nature (Zheng, 1992) and apatite to BiPO₄ in laboratory (Shemesh et al., 1988; Zheng, 1996).”

  • No adjustable parameters were introduced to the increment method after its establishment for calculations of oxygen isotope fractionation in different structures of crystalline minerals.

    “In addition, no adjustable parameters were introduced to the increment method after its establishment for calculations of oxygen isotope fractionation in the different structures of crystalline minerals (Zheng, 1991, 1992, 1993a, 1993b, 1993c, 1995, 1996, 1997, 1998, 1999).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
