Minerals

Magnetite is rock mineral and one of the most importan iron ore minerals with chemical formula is iron(II,III) oxide, Fe2+Fe3+2O4 .It also Magnetite is as the name magnetic minerals to attracted to a magnet. It is the most magnetic natural occuring minerals in the World. Small grains of magnetite occur in almost all igneous and metamorphic rocks.

Hematite is a mineral and a common form of iron oxide. It is known for its distinctive reddish-brown to black metallic luster. The name...

Possibly the earliest ore of copper, malachite is believed to have been mined in the Sinai and eastern deserts of ancient Egypt from as early as 3000 BCE. Single crystals are uncommon; when found, they are short to long prisms.

An important rock-forming mineral, dolomite is named after the French mineralogist Déodat Gratet de Dolomieu. It is a colorless to white, pale brown, grayish, reddish, or pink mineral. Its crystals are commonly rhombohedral or tabular, often have curved faces, and sometimes cluster in saddle-shaped aggregates.

Calcite is a rock-forming mineral with a chemical formula of CaCO3. It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere.

“Feldspar” is the name of a large organization of rock-forming silicate minerals that make up over 50% of Earth’s crust. They are discovered in igneous, metamorphic, and sedimentary rocks in all components of the sector. Feldspar minerals have very comparable structures, chemical compositions, and bodily properties. Common feldspars consist of orthoclase (KAlSi3O8), albite (NaAlSi3O8), and anorthite (CaAl2Si2O8).

Quartz is one of the most famous minerals on the earth. It occurs in essentially all mineral environments, and is the crucial constituent of many rocks. Quartz is likewise the maximum varied of all minerals, taking place in all distinct bureaucracy, habits, and colorings. There are more range names given to Quartz than any other mineral. Although the Feldspars as a group are more regular than Quartz, as an man or woman mineral Quartz is the maximum commonplace mineral.

Chlorite is the organization name for approximately 10 related minerals. However, the time period Chlorite may be used each to explain the organization in fashionable, or as a specific term to explain any inexperienced member of the Chlorite institution whose precise identity isn't always realistic to be decided.

Muscovite is the most common mineral of the mica own family. It is an essential rock-forming mineral present in igneous, metamorphic, and sedimentary rocks. Like other micas it with no trouble cleaves into skinny transparent sheets.

Biotite is the most common mica mineral and also known as black mica, a silicate mineral in the common mica group. Approximate chemical formula K (Mg, Fe). Biotite can be found in massive crystal layers weighing several hundred pounds. It is abundant in metamorphic rocks (both regional and contact), pegmatites, and also in granites and other invasive magmatic rocks. Biotite usually occurs in brown to black, dark green variety.

Mica, any of a collection of hydrous potassium, aluminum silicate minerals. It is a kind of phyllosilicate, showing a -dimensional sheet or layer structure. Among the most important rock-forming minerals, micas are located in all 3 foremost rock types—igneous, sedimentary, and metamorphic.

Clay minerals are the function minerals of the earths close to floor environments. They shape in soils and sediments, and through diagenetic and hydrothermal alteration of rocks. Water is essential for clay mineral formation and most clay minerals are defined as hydrous alumino silicates.
