Definition
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone
  
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar

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
  
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

Granite vs Arkose 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 Arkose characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granite and Properties of Arkose. Learn more about Granite vs Arkose 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 Arkose include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Granite and Arkose, they have various applications in construction industry. The uses of Granite in construction industry include As dimension stone and that of Arkose include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Granite and Arkose
Here you can know more about Granite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granite and Arkose 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 Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Granite vs Arkose, 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, Arkose is available in reddish brown colors. Appearance of Granite is Veined or Pebbled and that of Arkose is Rough and Dull. Properties of rock is another aspect for Granite vs Arkose. Hardness of Granite and Arkose is 6-7. 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 Arkose are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granite and Arkose is white. The specific heat capacity of Granite is 0.79 kJ/Kg K and that of Arkose is Not Available. 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 Arkose is heat resistant, impact resistant, pressure resistant.
