Dalnegorskoe (boron)
Primorsky Krai, Dalnegorsk district (Taukha terrane), Russia
SkarnsB (Pb-Zn)
- Type
- Borosilicate skarn (danburite, datolite)
South Sikhote-Alin metallogenic subprovince, with boron, tin and Pb-Zn deposits related to Late Cretaceous and Palaeocene granitic magmatism. Lead, very homogeneous across the subprovince, comes mostly from Mesozoic sedimentary sequences of the accretionary complexes, with a variable mantle input depending on the deposit. Indicative coordinates.
