Chalbinskoe
Komsomolsk ore district, Khabarovsk Krai (Myaochan volcano-tectonic depression), Russia
Other hydrothermalSn (Bi)
- Type
- Low-sulfide, bismuth-rich tin ore
Khingan-Badzhal-Komsomolsk metallogenic zone (Late Cretaceous, 95-85 Ma), formed at a transform margin. Its lead, much less radiogenic than that of the South Sikhote-Alin subprovince, would involve 70 to 90 % mantle lead according to Chernyshev et al. (2025). Hornfelsed silty sandstones with chert and spilite lenses, bounded to the west by the Chalba granite massif (94-86 Ma monzogranites); galena scarce, as small nodules in quartz. Ore dated at 85 ± 5 Ma (K-Ar on muscovite). Deposit not located: the place cited in the source could not be tied to reliable coordinates.
