- Type
- Amphibolite-hosted scheelite, related to a Jurassic granite
Recently discovered large tungsten deposit (66,500 t at 0.23 % WO3); all orebodies lie in Paleoproterozoic amphibolites of the Dajinshan Formation, without direct contact with the granite (158.8 Ma). Scheelite dated at 157.9 ± 6.7 Ma (Sm-Nd isochron), molybdenite at 158.1 Ma. Magmatic fluid re-equilibrated with the metamorphic rocks; scheelite εNd about -14.6: deep crustal material. Mindat coordinates.
