3 valid minerals.

Detailed Mineral List:

'K Feldspar'
Reference: Minato et al (1956) Mineralogical Journal, 1, 337-347.
Pyrite
Formula: FeS2
Description: Reported just as "FeS2" (pyrite or marcasite), but probably corresponds to the "framboidal pyrite" described from similar environment in numerous other japanese localities.
Reference: Minato et al (1956) Mineralogical Journal, 1, 337-347.
Quartz
Formula: SiO2
Reference: Minato et al (1956) Mineralogical Journal, 1, 337-347.
Vivianite
Formula: Fe2+3(PO4)2 · 8H2O
Reference: (Vivianite concretions from here are represented in innumerable japanese collections.)
