The Silicate Minerals [1]
Did you know that silicates like quartz and clay are among Earth’s most important natural resources? Imagine a world without glass, bricks, pottery, or computers – all of these rely on silicate minerals. These valuable materials make up 95% of the Earth’s crust.
Silica tetrahedra, made up of silicon and oxygen, form chains, sheets, and frameworks, and bond with other cations to form silicate minerals.. X-ray diffraction (XRD) allows scientists to determine the crystal structure of minerals.
– breakage in crystal structure of certain minerals along planes where atomic bonds are weakest. – the outermost layer of Earth; the surface layer of a planet
Earth’s Crust: Elements, Minerals and Rocks [2]
In the previous article in geography section, we have discussed in detail about the interior of the earth. We have seen different layers like crust, core, and mantle
In this article, we focus on how to learn fast the composition of the earth’s crust – i.e, different elements, minerals, and rocks.. – The earth is composed of various kinds of elements.
– The rest is constituted by elements like titanium, hydrogen, phosphorous, manganese, sulphur, carbon, nickel and others.. – The elements in the earth’s crust are rarely found exclusive but are usually combined with other elements to make various substances.
3.4: Silicate Minerals [3]
Minerals are categorized based on their composition and structure. Silicate minerals are built around a molecular ion called the silicon-oxygen tetrahedron
Silicate minerals form the largest group of minerals on Earth, comprising the vast majority of the Earth’s mantle and crust. Of the nearly four thousand known minerals on Earth, most are rare
These are generally called the rock-forming minerals.. The silicon-oxygen tetrahedron (SiO4) consists of a single silicon atom at the center and four oxygen atoms located at the four corners of the tetrahedron
Silicates [4]
The most abundant elements in the Earth’s crust are oxygen (46.6%) and silicon (27.7%). Minerals which combine these two elements are called silicates, and combined they are the most abundant minerals on the Earth
They most often contain members of the Big 8 elements. The table below is an example of such organization from Lutgens and Tarbuck.

– It is found commonly on earth, while quartz comes second.. – Silicate minerals form more than 90% of the crust.
– It is found on metamorphic, sedimentary, and igneous rocks across the world.. RRB Group D Notification is expected to be released soon
2.4 Silicate Minerals – Physical Geology [6]
The vast majority of the minerals that make up the rocks of Earth’s crust are silicate minerals. These include minerals such as quartz, feldspar, mica, amphibole, pyroxene, olivine, and a great variety of clay minerals
These are arranged such that planes drawn through the oxygen atoms form a tetrahedron (Figure 2.6). Since the silicon ion has a charge of +4 and each of the four oxygen ions has a charge of –2, the silica tetrahedron has a net charge of –4.
The simplest silicate structure, that of the mineral olivine, is composed of isolated tetrahedra bonded to iron and/or magnesium ions. In olivine, the –4 charge of each silica tetrahedron is balanced by two divalent (i.e., +2) iron or magnesium cations
Mineral Mondays: Silicates [7]
From the sand underneath our feet, to the watches on our wrists, we can’t escape the undeniable influence of silicates. Roughly 90 percent of Earth’s crust is made up of silicate minerals
Silicates have a distinct crystal shape: four oxygen atoms bonded to a silicon atom create a pyramid-like structure called a tetrahedron. Other elements like magnesium, calcium, and aluminum can attach themselves to this tetrahedron
As molten magma begins to harden, crystals slowly form. Other silicates can form in the spaces between rocks
Mineral – Silicates, Crystalline, Structure [8]
The silicates, owing to their abundance on Earth, constitute the most important mineral class. Approximately 25 percent of all known minerals and 40 percent of the most common ones are silicates; the igneous rocks that make up more than 90 percent of Earth’s crust are composed of virtually all silicates.
It is composed of a central silicon cation (Si4+) bonded to four oxygen atoms that are located at the corners of a regular tetrahedron. The terrestrial crust is held together by the strong silicon-oxygen bonds of these tetrahedrons
The positive charge (+4) of each silicon cation is satisfied by its four bonds to oxygen atoms. Each oxygen ion (O2–), however, contributes only one-half of its total bonding energy to a silicon-oxygen bond, so it is capable of also bonding to the silicon cation of another tetrahedron
3 Minerals – An Introduction to Geology [9]
At the end of this chapter, students should be able to:. – Derive basic atomic information from the Periodic Table of Elements.
– List common non-silicate minerals in oxide, sulfide, sulfate, and carbonate groups.. – Identify minerals using physical properties and identification tables.
In geology, the classic definition of a mineral is: 1) naturally occurring, 2) inorganic, 3) solid at room temperature, 4) regular crystal structure, and 5) defined chemical composition. Some natural substances technically should not be considered minerals, but are included by exception
Earth’s Minerals (Book): Silicate Minerals [10]
One silicon atom bonds to four oxygen atoms to form a pyramid. Silicate minerals make up over 90 percent of Earth’s crust!
These elements include calcium, iron, and magnesium.. Silicate minerals are divided into six smaller groups
Feldspar and quartz are the two most common silicates. In beryl, the silicate pyramids join together as rings
The Silicate Tetrahedron [11]
The silicate anion is made of four large oxygen atoms and one small silicon atom that pack themselves together to occupy the smallest possible space. This shape, with big oxygen atoms at four corners of the structure and the silicon atom at the center, is known as the silicate tetrahedron
To make a stable compound the silicate tetrahedron must therefore combine to neutralize this extra charge, which can happen in one of two ways:. (1) Oxygen can form bonds with cations (positively charged ions)
Mg2+, the silicate tetrahedron makes a mineral called olivine (mg2)sio4. (2) Two adjacent tetrahedra can share an oxygen atom, making a complex anion with the formula (si2o7)6-

I would imagine that there are students in the class who did not take chemistry in high school or transfer it in from another college. Some fundamental knowledge of chemistry will be required and the lectures and text should provide you with sufficient background
This is because past experience suggests that additional material is needed in this section to bring everyone up to about the same level of understanding. One goal is to make you familiar with some of the important Earth Materials; the amethyst crystals shown above have been highly prized for their esthetic quality
The following classification will help define the states in which matter can occur.. Read through this material until you come to the section dealing with rocks.

Silicate mineral [16]
Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth’s crust.[1][2][3]
Silica is found in nature as the mineral quartz, and its polymorphs.. On Earth, a wide variety of silicate minerals occur in an even wider range of combinations as a result of the processes that have been forming and re-working the crust for billions of years
Living organisms also contribute to this geologic cycle. For example, a type of plankton known as diatoms construct their exoskeletons (“frustules”) from silica extracted from seawater
3.1 Silicate Mineral Groups – A Practical Guide to Introductory Geology [17]
The vast majority of the minerals that make up the rocks of Earth’s crust are minerals. These include minerals such as quartz, feldspar, mica, amphibole, pyroxene, olivine, and a variety of clay minerals
The bonds in a silica tetrahedron have some of the properties of covalent bonds and some of the properties of ionic bonds. As a result of the ionic character, silicon becomes a cation (with a charge of +4) and oxygen becomes an anion (with a charge of –2)
As we will see later, silica tetrahedra (plural of tetrahedron) link together in a variety of ways to form most of the common minerals of the crust.. The element (Si) is one of the most important geological elements and is the second-most abundant element in Earth’s crust (after oxygen)
The Eight Most Abundant Elements in the Earth’s Crust [18]
The outermost surface of the Earth is called the lithosphere, or crust. This rigid layer contains both the oceans and landmasses
There are 92 naturally occurring elements, from hydrogen to uranium, and the earth’s crust contains nearly all of them.. Recall that an element is a substance unable to be broken further by chemical means
On the periodic table, elements are listed by a symbol, such as O for oxygen.. When two or more elements combine, a compound is formed
