Kolari mine (Nagpur)
Maharashtra, Nagpur district, India
OtherZn
- Type
- Stratabound zinc in metasediments
Zn deposit of Early (?) Proterozoic age in a dominantly clastic metasedimentary terrane, metamorphosed to greenschist facies. Palmer and Slack (1989, Table 1): tourmaline at -13.02 ‰. 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.
