Kuga district, Yamaguchi Prefecture (about 50 km south-west of Hiroshima), Japan
SkarnsW
- Type
- Scheelite skarn (scheelite type, ilmenite series)
Scheelite skarn in nearly pure limestone lenses of the Triassic Kuga group sediments, in the aureole of an Upper Cretaceous granodiorite to monzogranite batholith; Akemidani orebodies 100 to 300 m above the contact. Ore poor in ferric iron and sulfur, nearly Mo-free scheelite: reducing conditions linked to an ilmenite-series magma. Formed at about 390 ± 60 °C (sphalerite-galena) and about 1 kb. Coordinates estimated within the Kuga district. Indicative coordinates.
