Granite vs Andesite 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 Andesite 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. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. 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 Andesite information and Granite vs Andesite characteristics in the upcoming sections.

Granite vs Andesite 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 Andesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granite and Properties of Andesite. Learn more about Granite vs Andesite 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 Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Granite and Andesite, they have various applications in construction industry. The uses of Granite in construction industry include As dimension stone and that of Andesite include Cobblestones, Construction aggregate, For road aggregate.

More about Granite and Andesite

Here you can know more about Granite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granite and Andesite 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 Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Granite vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Granite is Veined or Pebbled and that of Andesite is Dull and Soft. Properties of rock is another aspect for Granite vs Andesite. The hardness of Granite is 6-7 and that of Andesite is 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 Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granite and Andesite is white. The specific heat capacity of Granite is 0.79 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
