Formation

Formation
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.  
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Coal 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 Coal and Andesite Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Coal vs Andesite information and Coal vs Andesite characteristics in the upcoming sections.

Coal 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. Coal vs Andesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Andesite. Learn more about Coal vs Andesite in the next section. The interior uses of Coal include whereas the interior uses of Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Coal and Andesite, they have various applications in construction industry. The uses of Coal in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Andesite include Cobblestones, Construction aggregate, For road aggregate.

More about Coal and Andesite

Here you can know more about Coal and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Andesite consists of mineral content and compound content. The mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon 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 Sedimentary Rocks. When we have to compare Coal vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Coal is Veined or Pebbled and that of Andesite is Dull and Soft. Properties of rock is another aspect for Coal vs Andesite. The hardness of Coal is 1-1.5 and that of Andesite is 7. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite 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 Coal is black while that of Andesite is white. The specific heat capacity of Coal is 1.32 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.Coal is heat resistant whereas Andesite is heat resistant, pressure resistant, wear resistant.
