About FukuchiliteHide

Nobuyo Fukuchi

Formula:

Cu₃FeS₈

Colour:

Dark brownish gray

Lustre:

Sub-Metallic

Hardness:

6

Specific Gravity:

4.86

Crystal System:

Isometric

Member of:

Pyrite Group

Name:

Named in honor of Nobuyo Fukuchi (福地 信世) (15 July 1877, Shimokuta-ku, Tokyo, Japan - 22 May 1934), a Japanese geologist who studied many Kuroko-type ore deposits. He worked for the Furukawa Mining Company and later as a lecturer at the Imperial University.

Type Locality:

ⓘ Hanawa mine, Kazuno City, Akita Prefecture, Japan

Perhaps the same species as the earlier named villamaninite.
Bayliss (1989) thinks fukuchilite may be a ferroan villamaninite.
