Quartzite IntroductionFeaturesIgneous rocksSedimentary rocksMetamorphic rocks. Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content.

Quartzite Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. It forms when a quartz-rich sandstone, is altered by the heat, pressure, and chemical activity of metamorphism. These conditions recrystallize the sand grains and the silica cement that binds them together. The result is a network of interlocking quartz grains of incredible strength. The interlocking crystalline structure of quartzite makes it a hard, tough, durable rock.

Potassium Feldspar Quartz: Quartz is a common mineral in many metamorphic and felsic igneous rocks that, like the potassium feldspars, also has a non-metallic luster and hardness greater than glass. Unlike the potassium feldspars, however, quartz does not exhibit cleavage, which easily distinguishes it from feldspar minerals.he potassium feldspar group is composed of three mineral polymorphs, each having the same chemical composition, but slightly different crystal structures. Technically these are distinct minerals, but their physical properties are so similar that they are usually only identified as ‘potassium feldspar’ in the field.

Soapstone Soapstone is a metamorphic rock, also known as steatite or soaprock. The chief mineral in Soapstone is talc, but it also contains varying amounts of magnesium, chlorite, mica, quartz, and iron compounds. Soapstone is formed over time by heat, fluids, and extreme pressure without melting.This process creates a stone that is naturally non-porous.he chief mineral in Soapstone is talc, but it also contains varying amounts of magnesium, chlorite, mica, quartz, and iron compounds.

Quartz Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.[7]

The Silicate Minerals Quartz falls into a group of minerals called the silicates, all of which contain the elements silicon and oxygen in some proportion. Silicates are by far the most common minerals in Earth's crust and mantle, making up 95% of the crust and 97% of the mantle by most estimates. Silicates have a wide variety of physical properties, despite the fact that they often have very similar chemical formulas.

Magnetite Magnetite is a mineral and one of the main iron ores. With the chemical formula Fe3O4, it is one of the oxides of iron. Magnetite is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Today it is mined as ir

axial muscle intro Sometimes several of the naming criteria are combined into a single name. Thus, if you learn the muscle you have also learned its origin, insertion and action. For example, the flexor carpi radialis is a muscle that (1) flexes, (2) the wrist, (3) is on the side of the forearm closest to the radius.

Chemical Properties Although chemically spoken silica is an oxide, in Angloamerican mineralogical literature quartz and all other silica modifications are usually classified as silicates (based on a classification scheme established by Dana). The reasoning behind calling quartz a silicate is that it is built up by a network of SiO 4 tetrahedra. Silicates are classified according to the way SiO 4 tetrahedra are integrated into the crystal structure and if and how the tetrahedra are linked to each other, and according to that quartz is called a tectosilicate (network silicate or framework silicate).

Mineral Minerals are not equivalent to rocks. A rock is either an aggregate of one or more minerals, or not composed of minerals at all. Rocks like limestone or quartzite are composed primarily of one mineral— calcite or aragonite in the case of limestone, and quartz in the latter case.inerals can be described by various physical properties which relate to their chemical structure and composition. Common distinguishing characteristics include crystal structure and habit, hardness, lustre, diaphaneity, colour, streak, tenacity, cleavage, fracture, parting, and specific gravity.

Magnetite Crystal Description. Magnetite is an iron oxide mineral and a member of the Spinel group. Magnetite occurs in a variety of rock types and is often the main constituent in black sand. Magnetite is strongly magnetic, and naturally occurring magnetic Magnetite is known as Lodestone. Magnetite specimens are often covered in 'hairy' fragments of iron, which makes Magnetite a uniquely unusual collectors piece.
