High temperature veins mined since ancient times. Famous for its Japan-law quartz twinning (the original "Japan-law" locality). Old quartz specimens from here often bear the obsolete province name "Kai". In reality a group of many mines spread over several villages and mountain slopes, over parts of Kohfu city and neighboring Makioka town. The name "Otome mine" was often applied generically to material from many different mines in the Kinpuzan district.
Mineral ListMineral list contains entries from the region specified including sub-localities
20 valid minerals. 1 (FRL) - first recorded locality of unapproved mineral/variety/etc. 1 erroneous literature entry.
GeochronologyMineralization age: Miocene : 11.7 ± 0.4 Ma to 11.36 ± 0.86 Ma
Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
