Beiwagou
Western Palaeoproterozoic Liaodong rift, Liaoning, China
Other hydrothermalZn-Pb
- Type
- Brecciated Zn-Pb in Palaeoproterozoic marbles
Zn-Pb deposit in banded marbles of the Dashiqiao Formation (Liaohe Group): marble breccias cemented by sphalerite, galena and pyrite, with hydrothermal calcite and magnesite. Very unradiogenic lead (model age about 1900 Ma), extracted from its source in the Palaeoproterozoic, clearly distinct from the nearby Triassic Qingchengzi orefield. Indicative coordinates. Position read on the location map of Chen et al. (2005).
206Pb/204Pb isotope ratio, no unit Values of the same system
Standard : NIST SRM 981
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 15.745 ± 0.056 | 15.679 / 15.807 | 7 | pyrite, galena, sphalerite and hydrothermal calcite Mean and standard deviation recalculated from 7 analyses, Table 1.
