Wurtzite is a zinc and iron sulfide mineral with the chemical formula (Zn,Fe)S, a less frequently encountered structural polymorph form of sphalerite. The iron content is variable up to eight percent. [5] It is trimorphous with matraite and sphalerite. [2]

Wurtzite is a rare, high temperature polymorph of the common mineral Sphalerite. It forms at temperatures above 2192º F (1200º C) as hexagonal crystals. An ornamental stone known as Schalenblende (an intergrowth of Wurtzite, Sphalerite, and often Galena) is usually referenced with Wurtzite but is more often listed as a variety of Sphalerite.

wurtzite, a zinc sulfide mineral that occurs typically in Potosí, Bolivia; Butte, Mont.; and Goldfield, Nev. It is a rare and unstable (at temperatures below 1,020° C, [1,870° F]) hexagonally symmetrical modification of sphalerite , to which it inverts crystallographically; it may be made artificially from sphalerite by rapid cooling from ...

Wurtzite is a crystal structure that consists of a hexagonal close-packed arrangement of oxygen anions with metal cations occupying the tetrahedral interstices. It is found in oxides such as ZnO and BeO.

Wurtzite (ZnS) is a zinc sulfide mineral that is normally brownish black, orange brown, reddish brown, or black in color. Wurtzite is commonly used in manufacturing processes and can be found in veins of ironstone concretions from black shales.

Wurtzite (Zn,Fe)S c 2001-2005 Mineral Data Publishing, version 1 Crystal Data: Hexagonal. Point Group: 6mm. Crystals to 1.5 cm, commonly hemimorphic pyramidal {5052} and {1011}; also short prismatic to tabular {0001}; typically striated horizontally on {1010} and {1011}. The polytypes show steepening of the pyramid as the repeat
