Rudkins mine (Bagdad, Arizona)
Arizona, Bagdad, United States
Volcanogenic massive sulfidesCu-Zn
- Type
- Metamorphosed volcanogenic massive sulfides
Cu-Zn deposit of Early Proterozoic age in a dominantly metavolcanic terrane, metamorphosed to greenschist facies. Palmer and Slack (1989, Table 2): tourmaline at -15.71 ‰. Tourmalines of this kind of terrane range from -15.71 to -1.49 ‰ in the article; according to the authors, the boron source (continental crust, entrained seawater, evaporites) matters more than the formation temperature.
