Chatkalite is a copper, iron,

tetragonal crystal system and forms as rounded disseminations within tetrahedrite in quartz veins
.

Physical properties

Chatkalite can have sizes ranging from rounded grains of about 100

diaphaneity can be described as opaque. It does not exhibit any cleavage or twinning properties. Chatkalite is anisotropic which is characteristic of the stannite
group. Its anisotropic intensity is a weak shade of brown.

Occurrences

Chatkalite was first located in the sulfide bearing quartz veins of the Chatkal-Kuramin Mountains in eastern Uzbekistan in 1981. Chatkalite has also been located in few other places since then namely Ubertad Mine, Quirulvica Province of Santiago de Chuco, Peru, Mine McCoy, McCoy district, Lander County, Nevada US and Eugenia Maria Vein, Cerro Shortcut, Catamarca, Argentina. A few other minerals are also closely associated to chatkalite based on locality, these are cassiterite, hermisite and hessite.

Unique characteristics

One of the rare characteristic of chatkalite is the fact that it has quaternary

symmetries
that are all consistent with the same set of d spacings. The mineral chatkalite and mawsonite are considered highly specialized because they can produce cubic I tetragonal P, orthorhombic F, and orthorhombic P lattices.

Etymology

Chatkalite was discovered in 1981 around the Chatkal Mountains of Uzbekistan in an unknown locality. It was given the name chatkalite because of this region where it was discovered.
