Sphalerite rock
2.3 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations, plus an anion (a negatively charged ion (e.g., S 2−)) or an anion complex (e.g., SO 4 2−). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3+ (iron) and the anion is O 2− (oxygen). The two Fe 3+ ions have an overall charge of +6 and …Sphalerite (sometimes spelled sphaelerite) is a sulfide mineral with the chemical formula (Zn,Fe)S. It is the most important ore of zinc.Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits. It is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite ...

Sphalerite is the major ore of zinc and often found with the mineral Galena. When it is in pure form, with little or no iron, it produces clear to translucent crystals. The colors found in this mineral will vary, the pale yellow color is known as Cleiophane. The orange and red shades are known as Ruby Blende or Ruby Jack. Comments: Actinolite is a member of a series that contains varying amounts of calcium, magnesium, iron, and aluminum, and has a chemical formula of Ca2(Mg,Fe)5Si8O22(OH)2. Tremolite is the Mg end, and ferroactinolite the Fe end, with actinolite in the middle. Actinolites with more than 50% Fe are very rare.
