Metamorphic rocks are very hard and can be used in the construction industry. Rocks are used for various purposes starting from construction of roads, bridges, buildings to pot in kitchen, as a gem stone or just for decorating your garden. The Properties of Marble and Its Uses. It is used for its optical properties in cosmetics, paint, and paper. The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical change. Rocks used in Road Igneous Rocks granite, basalt, gabbro and the most important species used in the best way to carry big weights. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. METAMORPHIC ROCKS Uses of Metamorphic Rocks. They are also used for rip rap in coastal defence schemes. It is widely used for architectural construction, ornamental stone and monuments. They are also useful to geologists and other scientists with interest in studying the earth. Piece of slate, metamorphic rock Slate is a good roofing material, but people also use it for decorative gardening stones, as a base for snooker tables and it was used as a writing board (or writing slate) in the Victorian classroom. They may be used in minor constructions. In the metamorphic process, most minerals are … They are frequently chosen for building materials and artwork. Gneiss, marble, slate, schist and quartzite are some of the different types of metamorphic rocks. Decorative rocks such as marble can be used in homes for fireplaces and kitchen work surfaces. The major types of metamorphism are contact and regional. Sedimentary rocks . Teachers' Notes Types of Rock Igneous Rocks: Examples and Uses Sedimentary Rocks: Examples and Uses Metamorphic Rocks: Examples and Uses The Rock Cycle What is Geology? Rocks fall into three classes according to their origin: Igneous - Sedimentary - Metamorphic. Rocks are used for various purposes starting from construction of roads, bridges, buildings to pot in kitchen, as a gem stone or just for decorating your garden. It is having fine to coarse grains. Very few rocks have as many uses as marble. Type of Rocks Igneous Rocks Sedimentary Rocks Metamorphic Rocks 9. However, some rocks have rare properties. Organic sedimentary rocks, like coal, are energy resources. Metamorphic Rock . In the nature there are so many types of rocks are available which are used in construction and engineering purposes. Importance of geology in construction and prevent the hazards Satya Prakash 1, ... Metamorphic rocks: Metamorphic rocks are the product of metamorphism of pre-existing igneous, sedimentary or even metamorphic rocks (23). Igneous rocks are basically used in flooring, landscaping and construction projects. Gneiss uses in Construction and Medical Industry. Although it is relatively soft, it is fairly tough, and does not split easily. However, igneous rock uses are specific to its type, which is classified according to the formation process, mineral content, hardness, texture and other properties. Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks. Quartzite and marble are the most commonly used metamorphic rocks. But when it comes to usage all of them having different properties and parameters. Metamorphic Rocks Metamorphic rocks form when rocks undergo metamorphosis/changes due to heat and pressure. Hornfels uses in Construction and Medical Industry. Quartzite is very hard and is often crushed and used in building railroad tracks. During the formation of metamorphic rocks the changes that takes place includes in texture and structure (24). Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". Types of sedimentary rocks have surprising physical, everyday uses and uses in construction. Slate varies in colour but is generally grey. A rock may be thought of as a "mineral environment." Igneous Rock These Rocks are formed from an originally hot molten material through the process of cooling and crystallization.Silica is the dominant constituent of the Igneous rock.
