SkarnsZn-Pb-Fe (Cu)
- Type
- Distal Zn-Pb-Fe-(Cu) skarn
Distal skarn with rhodonite, actinolite and chlorite. Lithium in fluid inclusions shows a magmatic fluid at the prograde stage (rhodonite), made heavier at the retrograde stage by Rayleigh fractionation as hydrous minerals capture up to 70% of the lithium, phase separation during Zn-Pb deposition, then meteoric water input at late stages (light-yellow sphalerite, calcite). Indicative coordinates.
δ7Li in ‰ (per mil) Values of the same system
Standard : IRMM-016
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 6.69 ± 0.96 ‰ | 5.37 / 7.91 ‰ | 5 | rhodonite fluid inclusion leachates (prograde skarn) Mean and standard deviation recalculated from 5 samples, Table 1. The abstract gives +5.37 to +7.31 ‰; the table reaches +7.91 ‰ (LZY-NO27), consistent with the published mean of +6.69 ‰. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… |
| 11.94 ± 0.46 ‰ | 11.48 / 12.54 ‰ | 4 | actinolite fluid inclusion leachates (retrograde skarn) Mean and standard deviation recalculated from 4 samples, Table 1. The text states n = 5, but LZY-NO12 has no value; it also gives +11.69 ‰ as the minimum whereas LZY-NO24 is +11.48 ‰. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… |
| 11.18 ± 0.58 ‰ | 10.44 / 11.66 ‰ | 4 | black and reddish-brown sphalerite fluid inclusion leachates Mean and standard deviation recalculated from 4 samples, Table 1. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… |
| 6.75 ‰ | 1 | light-yellow sphalerite fluid inclusion leachates One analysis (LZY-NO11), Table 1; external, probably meteoric, fluid input. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… | |
| 11.17 ± 1.79 ‰ | 9.78 / 13.19 ‰ | 3 | galena fluid inclusion leachates Mean and standard deviation recalculated from 3 samples, Table 1. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… |
| 5.17 ± 0.99 ‰ | 3.95 / 6.49 ‰ | 6 | calcite fluid inclusion leachates (late stage) Mean and standard deviation recalculated from 6 samples, Table 1. The discussion quotes +3.47 ‰ as the lowest value, not found in the table. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… |
| −5.97 ‰ | 1 | rhodonite (mineral) One analysis (LZY-NO27), Table 2; 1.04 µg/g Li. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… | |
| 1.71 ‰ | 1 | actinolite (mineral) One analysis (LZY-NO30), Table 2; 11.10 µg/g Li. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… | |
| −3.7 ‰ | 1 | sphalerite (mineral) One analysis (LZY-NO6), Table 2; 3.76 µg/g Li. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… | |
| −4.7 ‰ | 1 | calcite (mineral) One analysis (LZY-NO3), Table 2; 2.41 µg/g Li. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… | |
| −3.32 ‰ | 1 | unmineralised host marble One analysis (M1), Table 2; 0.17 µg/g Li (the text also gives 1.03 µg/g). The host rock cannot supply the heavy lithium of the fluids. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… |

| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 1.84 ± 0.01 ‰ | 1.83 / 1.85 ‰ | 2 | rhodonite fluid inclusion leachates Mean of 2 samples, Table 1; positive values typical of magmatic fluids. The abstract gives +1.82 to +1.83 ‰. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… |
| 0.49 ‰ | 1 | actinolite fluid inclusion leachates One analysis (LZY-NO30), Table 1; lower, decreased by crystallisation of Cl-bearing hydrous minerals. | Xu et al. (2021), Lithium and chlorine isotopic constraints on fluid sources and evolutio… |
