Sakuraiite

This page is currently not sponsored. Click here to sponsor this page.
Dr. Kinichi Sakurai
Formula:
(Cu,Zn,Fe)3(In,Sn)S4
Note: The formula is also given as (Cu,Zn,Fe,In,Sn)S, as suggested by Kissin & Owens (1986). The correct formula appears uncertain since the crystal structure has not been determined yet.
Colour:
Greenish steel-grey
Lustre:
Metallic
Hardness:
4
Crystal System:
Isometric
Name:
Named in 1965 by Akira Kato in honor of Dr. Kin-ichi Sakurai (December 11, 1912, Tokyo – October 6, 1993), after Kin-ichi Sakurai, amateur mineralogist of Tokyo. He described and/or provided type material for half a dozen species. The mineral kinichilite is also named in his honor.
Structurally related to the Sphalerite Group.
Compare also ishiharaite.
