Formation

Formation
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.   
Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

Anthracite vs Granite 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 Anthracite and Granite Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone. 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 Anthracite vs Granite information and Anthracite vs Granite characteristics in the upcoming sections.

Anthracite vs Granite 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. Anthracite vs Granite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anthracite and Properties of Granite. Learn more about Anthracite vs Granite in the next section. The interior uses of Anthracite include Not yet used whereas the interior uses of Granite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Anthracite and Granite, they have various applications in construction industry. The uses of Anthracite in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Granite include As dimension stone.

More about Anthracite and Granite

Here you can know more about Anthracite and Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Granite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Granite, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Granite is available in black, grey, orange, pink, white colors. Appearance of Anthracite is Veined or Pebbled and that of Granite is Veined or Pebbled. Properties of rock is another aspect for Anthracite vs Granite. The hardness of Anthracite is 1-1.5 and that of Granite is 6-7. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anthracite is black while that of Granite is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Granite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anthracite is heat resistant, water resistant whereas Granite is heat resistant, wear resistant.
