Zinc sulphide; -- called also blende, black-jack, false galena, etc. See Blende (a).
A zinc ore mineral, commonly found in volcanic massive sulphide deposits and composed of zinc, iron and sulphur.
A yellow, brown, or black mineral with the chemical formula (Zn,Fe)S.
Yellowish to dark brown, occasionally translucent mineral composed of zinc and sulfur. It is the principal ore of zinc.
an ore that is the chief source of zinc; consists largely of zinc sulfide in crystalline form
The major ore mineral of zinc (ZnS).
A mineral composed of zinc sulfide (ZnS). The most important ore mineral of zinc.
A yellow, brown, or black isometric mineral. It is a widely distributed ore of zinc, commonly associated with galena in veins and other deposits.
Naturally occurring zinc ore (zinc sulphide).
A mineral composed of zinc, sulphur and some iron and the main source of zinc; colour ranges from yellow to black ("black jack") as iron content increases.
A zinc sulphide mineral; the most common ore mineral of zinc.
Zinc sulphide which is the principal ore of zinc [Zn]. Sphalerite was often called 'black jack', 'resin jack', or 'zinc blende', because of its appearance and the variation in colours. Click here to see an example.
Sphalerite (ZnS) is a gay mineral that is the chief ore of zinc. It consists largely of zinc sulfide in crystalline form but almost always contains variable iron. When iron content is high it is an opaque black variety, marmatite ((Zn,Fe)S).
