Kutinaite (original) (raw)

Bindi & Makovicky (2015) suggest the formula (K,Tl)0.25Cu14Ag6As6.75.
Originally assumed to be Cu2AgAs.

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).

This map shows a selection of localities that have latitude and longitude coordinates recorded. Click on the symbol to view information about a locality. The symbol next to localities in the list can be used to jump to that position on the map.

- This locality has map coordinates listed. - This locality has estimated coordinates. ⓘ - Click for references and further information on this occurrence. ? - Indicates mineral may be doubtful at this locality. - Good crystals or important locality for species. - World class for species or very significant. (TL) - Type Locality for a valid mineral species. (FRL) - First Recorded Locality for everything else (eg varieties). Struck out - Mineral was erroneously reported from this locality. Faded * - Never found at this locality but inferred to have existed at some point in the past (e.g. from pseudomorphs).

All localities listed without proper references should be considered as questionable.
