Bailingshan
Xinjiang, East Tianshan, Aqishan-Yamansu belt (about 144 km SE of Shanshan), China
IOCGFe (Cu)
- Type
- Submarine volcanic-hosted iron oxide with skarn
Iron deposit (13.065 Mt at 44.94 % Fe) in three stratabound bodies within andesitic tuffaceous breccias of the Upper Carboniferous Tugutublak Formation (lava dated at 324.1 ± 2.1 Ma), intruded by 318 to 307 Ma granitoids; magnetite and hematite, minor pyrite and chalcopyrite, sodic then potassic alteration before iron. Zhang et al. (2018): tourmaline from +1.7 to +6.6 ‰, mostly magmatic fluid with a minor basinal brine component; Palaeozoic arc basin.

| 2.9 ± 0.7 ‰ | 1.7 / 4.1 ‰ | 16 | tourmaline I of quartz-K-feldspar nodules in potassic-altered granite Mean and standard deviation recalculated from 16 analyses, +1.7 to +4.1 (BL-049 +3.3; BL-049 +3.2; BL-049 +2.7; BL-049 +3.3; BL-049 +3.5; BL-049 +3.9; BL-049 +1.7; BL-049 +2.1; BL-049 +2.4; BL-049 +4.1; BL-049 +4.1; BL-049 +2.4; BL-049 +2.2; BL-049 +2.2; BL-049 +2.6; BL-049 +2.8). Schorl to schorl-dravite. Fluid calculated at +3.3 to +5.7 ‰ at 550 °C (Meyer et al., 2008). | Zhang et al. (2018), Discriminating hydrothermal fluid sources using tourmaline boron iso… |
| 5.1 ± 1 ‰ | 3.5 / 6.6 ‰ | 19 | tourmaline II of epidote veinlets cutting potassic-altered volcanics Mean and standard deviation recalculated from 19 analyses, +3.5 to +6.6 (BL-064 +4.7; BL-064 +6.1; BL-064 +6.6; BL-064 +4.3; BL-064 +5.9; BL-064 +6.0; BL-064 +5.9; BL-064 +4.1; BL-064 +4.5; BL-064 +3.5; BL-064 +4.0; BL-064 +4.7; BL-064 +4.2; BL-064 +6.4; BL-064 +5.7; BL-064 +4.0; BL-064 +4.4; BL-064 +5.4; BL-064 +5.7). Dravite; predates magnetite. Fluid calculated at +6.2 to +9.3 ‰ at 400 °C; shift from I to II explained by Rayleigh fractionation after about 70 % boron loss. | Zhang et al.
