Introduction
Minerals
Minerals are naturally occurring substances that are formed through geological processes and have a definite chemical composition and crystal structure. They are the building blocks of rocks and are essential for the functioning of our planet. Minerals have been used by humans for thousands of years for various purposes, such as construction, jewelry, and medicine. In this wiki page, we will explore the different types of minerals, their properties, and their uses.
Types of Minerals
There are over 4,000 known minerals, each with its own unique chemical composition and physical properties. However, they can be broadly classified into two main categories: silicate and non-silicate minerals.
Silicate Minerals
Silicate minerals are the most abundant type of minerals on Earth, making up about 90% of the Earth's crust. They are composed of silicon and oxygen, the two most abundant elements in the Earth's crust. Silicate minerals can be further divided into six groups based on their crystal structure: nesosilicates, sorosilicates, cyclosilicates, inosilicates, phyllosilicates, and tectosilicates.
Nesosilicates, also known as isolated tetrahedra, have a simple structure where each silicon atom is surrounded by four oxygen atoms. Examples of nesosilicates include olivine and garnet. Sorosilicates, or double tetrahedra, have two tetrahedra sharing one oxygen atom. Some common sorosilicates are epidote and zoisite.
Cyclosilicates, also known as ring silicates, have a ring structure where each silicon atom is bonded to three oxygen atoms. Beryl and tourmaline are examples of cyclosilicates. Inosilicates, or chain silicates, have a chain structure where each silicon atom is bonded to two oxygen atoms. Pyroxene and amphibole are examples of inosilicates.
Phyllosilicates, also known as sheet silicates, have a sheet structure where each silicon atom is bonded to four oxygen atoms. Mica and clay minerals are examples of phyllosilicates. Tectosilicates, or framework silicates, have a three-dimensional network structure where each silicon atom is bonded to four oxygen atoms. Quartz and feldspar are examples of tectosilicates.
Non-Silicate Minerals
Non-silicate minerals make up the remaining 10% of the Earth's crust. They are composed of elements other than silicon and oxygen, such as carbon, sulfur, and halides. Non-silicate minerals can be further divided into several groups, including native elements, sulfides, oxides, halides, carbonates, and sulfates.
Native elements are minerals that are composed of only one element, such as gold, silver, and copper. Sulfides are minerals that contain sulfur and a metal, such as pyrite and galena. Oxides are minerals that contain oxygen and a metal, such as hematite and magnetite.
Halides are minerals that contain a halogen element, such as fluorite and halite. Carbonates are minerals that contain carbon and oxygen, such as calcite and dolomite. Sulfates are minerals that contain sulfur and oxygen, such as gypsum and barite.
Properties of Minerals
Minerals have several physical and chemical properties that can be used to identify and classify them. These properties include color, streak, luster, hardness, cleavage, fracture, and specific gravity.
Color is the first property that comes to mind when we think of minerals. However, it is not a reliable property for identification as many minerals can have the same color. Streak, on the other hand, is the color of a mineral's powder when it is rubbed against a hard surface. It is a more reliable property for identification.
Luster refers to the way a mineral reflects light. It can be metallic, non-metallic, or sub-metallic. Hardness is a measure of a mineral's resistance to scratching and is measured on the Mohs scale from 1 (softest) to 10 (hardest). Cleavage is the tendency of a mineral to break along flat, smooth surfaces, while fracture is the way a mineral breaks when it does not have a cleavage plane.
Specific gravity is the ratio of a mineral's weight to the weight of an equal volume of water. It can help distinguish between minerals with similar physical properties.
Uses of Minerals
Minerals have been used by humans for various purposes throughout history. Some of the most common uses of minerals include construction, jewelry, and medicine.
Construction materials, such as sand, gravel, and limestone, are made from minerals. Minerals are also used in the production of cement, which is used to make concrete, a key building material. Metals, such as iron, copper, and aluminum, are extracted from minerals and used in the construction of buildings, vehicles, and other structures.
Minerals are also used in the production of jewelry. Gemstones, such as diamonds, rubies, and emeralds, are minerals that are cut and polished to make beautiful pieces of jewelry. Other minerals, such as gold and silver, are used to make jewelry as well.
Medicinal minerals, also known as mineral supplements, are used to treat various health conditions. For example, calcium supplements are used to strengthen bones, while iron supplements are used to treat anemia. Minerals are also used in the production of pharmaceutical drugs, such as magnesium for laxatives and zinc for cold remedies.
