A Glossary of Rock and Mineral Terminology

feldspar: A mineral group that consists of abundant, light-colored, rock-forming silicate minerals. The most common minerals are microcline, orthoclase, and plagioclase. ferromagnesian: Containing iron and magnesium. Applied to certain dark silicate minerals, especially amphibole, pyroxene, biotite, and olivine. fiber:

Hydrothermal mineral deposit

Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create metallic-rich fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals. In some occurrences, minerals can be extracted for a profit by mining.

Shale

Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al 2 Si 2 O 5 4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers less than one centimeter in thickness.

1 Reaction With Air . Metals react with oxygen to form metal oxide. metal +oxygen → metal oxide. Na + O2→ Na2O. Mg+ O2→ MgO. If we notice the nature of oxides the Metal oxides are basic in nature, i.e., they turn red litmus blue but some metal oxides proved to be amphoteric (i.e they have acidic and basic character).

Silicon

The silicate form includes asbestos, granite, hornblende, feldspar, clay and mica. Elemental silicon is produced commercially by reducing sand with carbon in an electric furnace.
