Honghai (Kalatag district)
Eastern Tianshan, Xinjiang (Kalatag island arc), China
Volcanogenic massive sulfidesCu-Zn (Au)
- Type
- Cu-Zn-Au volcanogenic massive sulfide (VMS)
VMS deposit of the Early Palaeozoic Kalatag island arc (440 to 430 Ma), later overprinted by epithermal mineralisation. Copper becomes heavier from deep Cu ores to shallow Zn ores (kinetic fractionation during chalcopyrite deposition), and zinc becomes heavier from the centre to the periphery of the hydrothermal system. Indicative coordinates.

| 0.26 ± 0.32 ‰ | −0.28 / 0.7 ‰ | 16 | mineral separates from massive, disseminated and stockwork ores (pyrite, chalcopyrite, sphalerite) Mean and standard deviation recalculated from 16 samples, Table 1. ZK0302-18 (+3.80 ‰) excluded, attributed to secondary mineralisation. The abstract reports 16 separates, the table lists 17. | Deng et al.
