About FukuchiliteHide
This section is currently hidden. Click the show button to view.
Colour:
Dark brownish gray
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.
Perhaps the same species as the earlier named villamaninite.
Bayliss (1989) thinks fukuchilite may be a ferroan villamaninite.
