How many abundant minerals are there

These six most abundant minerals are feldspar, quartz, pyroxenes, amphiboles, mica and olivine. Characteristics of some of the major minerals Feldspar: Silicon and oxygen are major elements of all types of feldspar. Sodium, potassium, calcium, aluminium, etc are found in specific feldspar varieties. It has light cream to salmon pink colour. It is commonly used in ceramics and glass making. Quartz: It is one of the most important components of sand and granite. It consists of silica and it is a hard mineral virtually insoluble in water.

It is usually white or colourless. They are used in the manufacturing of radio, radar, etc. Pyroxene: The common elements in pyroxene are Calcium, aluminium, magnesium, iron and silicon. It is commonly found in meteorites. Its colour is usually green or black. Amphibole: Aluminium, calcium, silicon, iron and magnesium are the major elements of amphiboles.

It is green or black in colour and is used in asbestos industries commonly. Hornblende is another form of amphiboles. Mica: It is made up of elements like potassium, aluminium, magnesium, iron, silicon, etc.

It is commonly found in igneous and metamorphic rocks. Mica is widely used in electronic instruments. Olivine: Magnesium, iron and silica are the major elements of olivine. The mineral silver is made up of only silver atoms and diamond is made only of carbon atoms, but most minerals are made up of chemical compounds. Each mineral has its own chemical formula. Halite, pictured in the Figure 2.

Quartz is always made of two oxygen atoms bonded to a silicon atom, SiO 2. A hard mineral containing covalently bonded carbon is diamond, but a softer mineral that also contains calcium and oxygen along with carbon is calcite Figure below.

Some minerals have a range of chemical composition. Olivine always has silicon and oxygen as well as iron or magnesium or both, Mg, Fe 2 SiO 4. How physical properties are used to identify minerals is described in the lesson on Mineral Formation. Minerals are divided into groups based on chemical composition. Most minerals fit into one of eight mineral groups. Silicates are by far the largest mineral group. Feldspar and quartz are the two most common silicate minerals.

Both are extremely common rock-forming minerals. The basic building block for all silicate minerals is the silica tetrahedron, which is illustrated in Figure below. To create the wide variety of silicate minerals, this pyramid-shaped structure is often bound to other elements, such as calcium, iron, and magnesium. Silica tetrahedrons combine together in six different ways to create different types of silicates Figure below. Tetrahedrons can stand alone, form connected circles called rings, link into single and double chains, form large flat sheets of pyramids, or join in three dimensions.

The different ways that silica tetrahedrons can join together cause these two minerals to look very different. Native elements contain atoms of only one type of element. Only a small number of minerals are found in this category. Some of the minerals in this group are rare and valuable. Gold, silver, sulfur, and diamond are examples of native elements.

The basic carbonate structure is one carbon atom bonded to three oxygen atoms. Carbonates include other elements, such as calcium, iron, and copper. Calcite CaCO 3 is the most common carbonate mineral Figure below. Azurite and malachite, shown in the Figure below, are carbonates that contain copper instead of calcium.

Halide minerals are salts that form when salt water evaporates. Halite is a halide mineral, but table salt is not the only halide.

The chemical elements known as the halogens fluorine, chlorine, bromine, or iodine bond with various metallic atoms to make halide minerals see Figure below.

During impact, the meteorite was subjected to temperatures in excess of degrees F and pressures around 24 gigapascal, similar to what is found in the lower mantle. Bridgmanite was named in honor of Percy Bridgman, who won a Nobel Prize in for his research of materials at very high pressures. If asked this question on a quiz or test, make sure to look carefully at the wording before answering and be prepared to argue.

If you see the words "continent" or "continental crust" in the question, then your answer is most likely quartz. If you just see the word "crust," then the answer is probably feldspar. If the question does not mention the crust at all, go with bridgmanite.
