Definition
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite
  
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Formation
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
  
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.

Granodiorite vs Coal 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. Granodiorite vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granodiorite and Properties of Coal. Learn more about Granodiorite vs Coal in the next section. The interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Granodiorite and Coal, they have various applications in construction industry. The uses of Granodiorite in construction industry include As dimension stone and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Granodiorite and Coal
Here you can know more about Granodiorite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Coal consists of mineral content and compound content. The mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and 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. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Granodiorite is available in black, grey, orange, pink, white colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Granodiorite is Veined or Pebbled and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Granodiorite vs Coal. The hardness of Granodiorite is 6 and that of Coal is 1-1.5. The types of Granodiorite are Not Available whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite is white while that of Coal is black. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Coal 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.Granodiorite is heat resistant, wear resistant whereas Coal is heat resistant.
