Kutinaite

This page is currently not sponsored. Click here to sponsor this page.
Jan Kutina
Formula:
Ag6Cu14As7
Bindi & Makovicky (2015) suggest the formula (K,Tl)0.25Cu14Ag6As6.75.
Originally assumed to be Cu2AgAs.
Colour:
Grey, greyish-white, blue-grey
Lustre:
Metallic
Hardness:
Crystal System:
Isometric
Name:
Named in 1970 by J. Hak, Z. Johan, and Brian J. Skinner in honor of Dr. Jan Kutina (1924, Prague - 14 August 2008, Maryland, USA), geologist. He held academic positions at the Charles University in Prague and in the USA and Japan. His specialty was ore deposits and metallogenic research.
Restudy of the type material is necessary (Bindi & Makovicky, 2015).
