Introduction
A mineral is a naturally occurring, inorganic solid with a definite chemical composition and ordered internal structure. Minerals are found in rocks and other geological materials, such as sand, soil, and even water. Minerals can be identified by their physical properties, such as color, luster, hardness, and streak. They can also be identified by their chemical composition and crystal structure.
There are more than 4,000 known mineral species, but only about 30 of them make up most of the Earth’s crust. The other 3,970 or so minerals are considered rare and uncommon. Minerals can be divided into two categories: macrominerals and trace minerals. Macrominerals are minerals that are needed in large amounts, such as calcium and magnesium. Trace minerals are needed in smaller amounts, such as iron and zinc.
What is an Example of a Mineral?
Examples of common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite. Quartz is one of the most abundant minerals on Earth, and it has many uses in industry and jewelry making. Feldspar is another common mineral that is used in ceramics and glassmaking. Mica is a shiny, flaky mineral that is often used in construction materials, such as roofing shingles and insulation. Amphibole is a group of dark-colored minerals that are used as abrasives and polishing agents. Olivine is a greenish mineral that is found in some igneous rocks. Calcite is a white, crystalline mineral that is used in cement, concrete, and plaster.
Examples of uncommon minerals include apatite, sphalerite, pyrite, galena, and magnetite. Apatite is a blue-green mineral that is often used in fertilizer and toothpaste. Sphalerite is a yellow-brown mineral that is used in jewelry and optical instruments. Pyrite is a metallic-looking mineral that is sometimes referred to as “fool’s gold.” Galena is a lead sulfide mineral that is used in electronics and batteries. Magnetite is a black mineral that is composed of iron oxide and is attracted to magnets.
Rocks and other material can look like minerals, but they are not actually minerals. Rocks are made up of two or more minerals that are held together by chemical bonds. Examples of rocks include granite, basalt, and limestone. Soil is a mixture of organic matter, minerals, air, water, and living organisms. Sand is a loose collection of small particles of rock, mineral, and organic matter. Ice is a solid form of water, and it is not a mineral because it does not have a definite chemical composition.
The Basics of Minerals
Minerals have several characteristics that help to identify them. The color of a mineral can give clues about its composition, but it is not always reliable. Luster refers to the way light reflects off of the surface of a mineral. Hardness is a measure of how difficult it is to scratch a mineral, and streak is the color of the powder left behind when a mineral is scratched.
Minerals can be identified using a process called mineralogy. This involves examining a mineral’s physical and chemical properties, such as its color, luster, hardness, and streak, as well as its chemical composition and crystal structure. Mineralogists use special tools, such as magnifying glasses and microscopes, to examine minerals.
Minerals have many uses. Some minerals, such as quartz and feldspar, are used in the production of glass and ceramics. Other minerals, such as mica and olivine, are used in construction materials, such as roofing shingles and insulation. Still other minerals, such as calcite and apatite, are used in fertilizers and toothpaste. Minerals are also used in jewelry and electronics.
