10 Minerals That Have Metallic Luster ThoughtCo

Metallic luster looks like a shiny metal such as chrome, steel, silver, or gold. Metallic minerals are also always opaque. Non metallic minerals may be shiny and reflect light, however, they do not look like a metal. Surface color may be helpful in identifying minerals, although it can be quite variable even within a single mineral family.

20.1 Metal Deposits Physical Geology

They are called massive sulphide deposits because the sulphide minerals (including pyrite (FeS2) , sphalerite (ZnS), chalcopyrite (CuFeS 2), and galena (PbS)) are generally present in very high concentrations (making up the majority of the rock in some cases). The metals and the sulphur are leached out of the sea floor rocks by convecting groundwater driven by the

2.3 Mineral Groups Physical Geology

2.3 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations and 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). We group minerals into classes on the basis of their predominant anion or anion
