British Columbia, Kimberley (Belt-Purcell Basin), Canada
SEDEXPb-Zn-Ag
- Type
- Stratiform sedimentary exhalative Pb-Zn-Ag with tourmalinite pipe
Giant deposit of the lower Aldridge Formation (Mesoproterozoic), clastic turbidites cut by gabbro sills and dykes dated 1468 ± 3 Ma; middle to upper greenschist metamorphism (about 450 °C and 3.8 kbar). Discordant tourmalinite pipe below the western part of the orebody (1470 × 980 m, at least 450 m deep), rarer hanging-wall tourmalinites, chlorite-albite-pyrite alteration zone. Jiang et al. (1999): tourmalines from -11.1 to -2.9 ‰; boron from footwall clastic sediments and deep non-marine evaporites, variations mainly due to seawater entrainment and Rayleigh fractionation. Indicative mine coordinates, not published.

| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| −8.9 ± 1.4 ‰ | −10.5 / −6.4 ‰ | 12 | tourmaline of hanging-wall tourmalinites Mean and standard deviation recalculated from 12 analyses, -10.5 to -6.4 (JS-93-15A -9.9; JS-93-15B -8.2; JS-93-15C -6.4; JS-93-16A -10.5; JS-93-16B -9.8; JS-93-16C -9.4; JS-93-16D -9.9; JS-93-22A -9.8; JS-93-22B -9.9; JS-93-22C -7.3; JS-93-22D -6.9; JS-93-24 -8.7). Tourmalinites coeval with or later than the ores; highest values in the albitized zone. | Jiang et al. (1999), Boron isotope systematics of tourmaline formation in the Sullivan Pb… |
| −7.3 ± 1.7 ‰ | −11.1 / −2.9 ‰ | 30 | tourmaline of shallow footwall tourmalinites (less than 30 m below the orebody) Mean and standard deviation recalculated from 30 analyses, -11.1 to -2.9 (MP-93-1 -8.8; 3901-1 -7.6; 3802-1 -7.2; 4154DN-1 -9.2; 4154DN-2 -11.1; JS-93-51A -6.4; JS-93-51B -7.2; JS-93-51D -4.9; JS-93-53A -9.0; JS-93-53B -6.9; JS-92-27A -7.2; JS-92-31A -7.1; JS-92-31B -8.5; JS-93-32A -7.1; DS-77-81 -8.6; DS-78-52A -4.0; DS-78-52B -6.2; JS-93-25 -8.3; JS-92-29A -10.9; DS-76-105A -6.1; DS-76-105B -5.3; JS-94-16A -8.0; DS-76-10 -7.9; DS-76-11 -7.8; DS-76-13 -7.8; DS-77-131 -6.8; DS-78-57 -8.5; DS-76-12A -6.3; JS-81-70 -6.6; Sull-84-1 -2.9). JS-81-70 and Sull-84-1 (brown tourmaline disseminated in massive pyrrhotite) taken from Palmer and Slack (1989). The text gives -11.1 to -4.0 ‰ and a -7.5 ‰ mean, without Sull-84-1. | Jiang et al. (1999), Boron isotope systematics of tourmaline formation in the Sullivan Pb… |
| −7.5 ± 1.4 ‰ | −9.3 / −4.9 ‰ | 13 | tourmaline of deep footwall tourmalinites Mean and standard deviation recalculated from 13 analyses, -9.3 to -4.9 (JS-92-27D -6.6; JS-92-27F -8.8; JS-92-27I -8.5; JS-92-27N -7.9; JS-92-27R -8.5; JS-92-27W -5.4; JS-92-27X -4.9; JS-92-27AA -7.2; JS-92-27DD -7.6; JS-92-28B -8.7; JS-92-28D -8.1; JS-92-28F -6.1; JS-92-28G -9.3). Holes DDH 2375 and 6799, down to 556 m; some recrystallized at gabbro sill contacts. The text gives -9.4 to -4.9 ‰. | Jiang et al.
