5 Formation

5.1 Formation

Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Granite vs Shale Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Granite and Shale Reserves. Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Granite vs Shale information and Granite vs Shale characteristics in the upcoming sections.

Granite vs Shale Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Granite vs Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granite and Properties of Shale. Learn more about Granite vs Shale in the next section. The interior uses of Granite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Shale include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Granite and Shale, they have various applications in construction industry. The uses of Granite in construction industry include As dimension stone and that of Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.

More about Granite and Shale

Here you can know more about Granite and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granite and Shale consists of mineral content and compound content. The mineral content of Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Granite vs Shale, the texture, color and appearance plays an important role in determining the type of rock. Granite is available in black, grey, orange, pink, white colors whereas, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Granite is Veined or Pebbled and that of Shale is Muddy. Properties of rock is another aspect for Granite vs Shale. The hardness of Granite is 6-7 and that of Shale is 3. The types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granite and Shale is white. The specific heat capacity of Granite is 0.79 kJ/Kg K and that of Shale is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granite is heat resistant, wear resistant whereas Shale is heat resistant, impact resistant.
