Extract of sample "Definition of Igneous Rocks"

Download file to see previous pages Igneous rocks are made when molten rock material called magma cools and solidifies. Magma may be thought of like a molten rock but it is not regularly a simple molten fluid. Nonetheless, it is rather a multifaceted blend of molten solid materials, for example, crystals, rocks, as well as dissolved vapor. Magma’s chemical composition and physical properties such as viscosity and density are all important factors that control magma’s overall behavior, for instance, how fast or slow it will move, how explosive it will be, what minerals will form in it, and their grain sizes and physical interrelationships. In terms of chemical composition, all magmas except rare carbonites are rich in carbonate component. They are also silicate magmas in which the dominant component is silica (SiO2), which generally comprises 45 % or more by weight. Alumina (Al2O3), with its abundance in common igneous rocks anywhere between 13 and 18 %, is at a distant second.
Igneous rocks are categorized according to location, chemical composition, surface consistency, and mineralogy. Two significant factors used for the taxonomy of igneous rocks are the rock grain size, which largely depends on the cooling history, determines the texture and the mineral or chemical composition of the rock (Krebs, 2003 p. 95).
The identification of these rocks is majorly done by texture. The grain consistency of volcanic rocks comprising the size, distribution of mineral grains, shape, orientation, and the intergranular relationships will decide if the rock is designated as simple or pyroclastic lava, or a tuff. Subsequently, it also determines what minerals are found in what kind of igneous rock.

Definition

...?Definition The term “frenemy” refers to a person who is considered to be both a friend and an enemy. The term itself is a result of combining the words ‘friend’ and ‘enemy’. An example of a frenemy is someone who plays both the roles of a friend and enemy in regard to an individual friendship. In essence, there is a love and hate relationship between the two people (Voo, 2007); one moment, they are getting along just as friends should, but the next moment the two friends find themselves against each other. A frenemy is often treated accordingly, with everyone being conscious of what that person is. Another type of frenemy is a person who is considered to be a friend but is constantly putting others in their group down. It is the type...

Mineral and Rocks

... is the basis of their classification in different groups. The different silicate groups include Micas, Quartz, Amphibole group, Olivine group and Pyroxene group. Micas and Quartz contain Biotite and Muscovite groups. Moreover Feldspars which make half of the Earth crust are also silicate minerals and are further classified as Potassium Feldspar and Plagioclase. The mineral rocks have been classified into three basic groups on the basis of their origin; these groups are sedimentary rocks, igneous rocks, and metamorphic rocks. Certain natural processes resulted in the formation of these rocks. Magma is a molten material which is present deep inside the Earth and is molten because of the high temperatures inside the Earth. Magma is the source...

Sedimentary Rocks

.... Although there cover of the earth’s crust is extensive (about 75 per cent), sedimentary rocks only constitute about five per cent of the total volume of the crust. The earth’s crust mainly consists of the igneous and metamorphic rocks. Sedimentary rocks are vital sources of the natural resources such as coal and drinking water (Stille and Fichter, 2008). Formation of Sedimentary Rocks Sedimentary rocks are usually formed in areas where there is water or water had existed in one particular time. The dead materials of animals, plants, and pieces of rocks or minerals are then transported to these areas (water bodies) by wind, water, ice, or gravity where they are often dropped off and sink to the bottom. At the bottom of the water bodies...

Mineral and Rocks

... is Feldspar which also belongs to the group of silicate minerals. Mineral rocks have their own distinctive classification and are categorized into three groups – namely, 1) Metamorphic rocks, 2) Sedimentary rocks and 3) Igneous rocks. These rocks are formed by natural processes that take place on the Earth. Deep down in the Earth, we can find Magma which is a mixture of molten metal, gasses and rock which occurs in liquid form due to the very high temperature and pressure inside the Earth. Igneous rocks are formed from this Magma which is gradually thrust upward to the Earth’s surface and cools. On cooling, the liquid Magma gets settled in a layered pattern depending on the temperature and pressure involved and this is what is known...

Industrial Minerals and Rocks

The level of the natural resource base is an important determinant of the ability of a given country to realize expansionary growth and infrastructural development. In the international platform, the quota system determines how much export or import a country is entitled to. The main issue in this paper is to find out the impact of the allocated export quota for China on rare Earth metals and the effect this has on the global economic direction (Kogel, 2006). Rare minerals are instrumental in giving a country a bargaining power in the international world market. The current social, political and economic realignment taking place in the world is increasingly spreading to the different countries in the world. With the campaign again...

Rocks and Minerals

... Rocks and Minerals Discuss the properties of the sample with respect to Geotechnical Engineering Civil Engineering.Basalt Basalt is an extrusive type of igneous rock composed mainly of plagioclase and pyroxene minerals. Primary minerals of basalt are feldspar and hornblende. It is the most common rock in the earth’s crust.It isthe most common volcanic extrusion in oceanic crust around the world. Basalt can be black, dark gray or greenish black. It can be found in crustal extension zones such as mid oceanic ridges, lava flows, hot spot volcanic regions, lunar rocks and Martian volcanic region. Basalt is commonly used for gravels and it is not use in building or architecture as much as granite. Crushed basalt is commonly used as aggregate...

Rocks and Minerals in Indiana

...Rocks and Minerals in Indiana Introduction Rocks comprise of mineral grains that are usually mixed with other components presenting dissimilar properties. Conversely, minerals are considered natural chemical compounds and the properties that certain minerals possess arise from atomic arrangements and element components. Indiana is considered wealthy due to abundant mineral repositories and rocks. Rocks and minerals present within the state are regarded as the basis for the wealthy state of the populace. Indiana has different minerals and rocks, with the commonest rocks being igneous, Paleozoic and metamorphic rocks. Additionally, minerals occur in abundance within this state.

Volcanoes and other Igneous Features

...Jerry Ciacho May 08, Three Types of Faults A fault is a great fissure in the Earths crust where a part has been displaced against another part of the crust. This movement denotes that faults provide evidence that Earth is active. Fault movements are indications of great and potent forces deep under the ground. There are three known types of faults: the normal fault, reverse fault and strike-slip fault. Jointly, normal and reverse faults are referred to as dip-slip faults, since their movement happens along the direction of the dip, causing a movement going up and down respectively. Compression is the pressure force of a reverse fault. The hanging wall slides going up past the footwall. The pushing forces that cause reserve faults...
