Carbonate replacementPb-Zn
- Type
- Carbonate replacement (dolomitised and silicified marbles)
Large Pb-Zn deposit (131 Mt at 3.95 % Pb + Zn) of the Central Tianshan terrane, in marbles and silicified rocks of the Mesoproterozoic Kawabulake Group, in four ore zones; main stage at about 337 Ma, between 240 and 357 °C. Sphalerite δ66Zn and Zn/Cd ratio vary together from one zone to another: initial fluid at about -0.2 ‰, zinc remobilised from the Precambrian basement, Rayleigh fractionation along fluid pathways. Longitude read on the map of the publication, latitude estimated.

| −0.42 ± 0.07 ‰ | −0.48 / −0.32 ‰ | 4 | stage II-2 sphalerite, ore zone III Mean and standard deviation recalculated from 4 samples, Table 1. The text gives -0.42 to -0.32 ‰, the table -0.48 to -0.32 ‰: computed on the table. Lightest zone, close to the initial fluid. | Chen et al.

| −0.05 ± 0.23 ‰ | −0.39 / 0.07 ‰ | 4 | stage II-2 sphalerite, ore zone IV Mean and standard deviation recalculated from 4 samples, Table 1. The -0.39 ‰ value pulls the mean down. | Chen et al. (2025), Zinc isotopes trace the metal source and fluid flow pathways of the l… |
| −0.08 ± 0.03 ‰ | −0.11 / −0.06 ‰ | 4 | Carboniferous felsic intrusions (quartz diorite, diorite, dioritic porphyrite, granodiorite) Mean and standard deviation recalculated from 4 samples, Table 1. Not the zinc source according to the authors. | Chen et al. (2025), Zinc isotopes trace the metal source and fluid flow pathways of the l… |
| −0.19 ± 0.16 ‰ | −0.32 / −0.02 ‰ | 3 | Kawabulake Group host rocks (siltstone and two marbles) Mean and standard deviation recalculated from 3 samples, Table 1.
