- Type
- Metamorphosed stratiform Zn-Pb-Cu-Ag
Zn-Pb-Ag deposit of Late Proterozoic age in a dominantly clastic metasedimentary terrane, metamorphosed to amphibolite facies. Palmer and Slack (1989, Table 1): tourmaline at -12.11 and -11.94 ‰. Tourmalines of this kind of terrane range from -15.37 to -2.19 ‰ in the article; according to the authors, the boron source (continental crust, entrained seawater, evaporites) matters more than the formation temperature. Indicative coordinates, not published in the article.
