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
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 vs Anthracite 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 Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granite and Properties of Anthracite. Learn more about Granite vs Anthracite 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 Anthracite include Not yet used. Due to some exceptional properties of Granite and Anthracite, they have various applications in construction industry. The uses of Granite in construction industry include As dimension stone and that of Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Granite and Anthracite
Here you can know more about Granite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granite and Anthracite 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 Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Igneous Rocks. When we have to compare Granite vs Anthracite, 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, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Granite is Veined or Pebbled and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Granite vs Anthracite. The hardness of Granite is 6-7 and that of Anthracite is 1-1.5. 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 Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granite is white while that of Anthracite is black. The specific heat capacity of Granite is 0.79 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
