1 Definition

1.1 Definition

Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

5.1 Formation

Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

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.

Marble vs Coal 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 Marble and Coal Reserves. Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Marble vs Coal information and Marble vs Coal characteristics in the upcoming sections.

Marble 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. Marble vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Marble and Properties of Coal. Learn more about Marble vs Coal in the next section. The interior uses of Marble include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Marble and Coal, they have various applications in construction industry. The uses of Marble in construction industry include As dimension stone and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.

More about Marble and Coal

Here you can know more about Marble and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marble and Coal consists of mineral content and compound content. The mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, 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 Metamorphic Rocks. When we have to compare Marble vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Marble is available in black, blue, brown, grey, pink, white colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Marble is Veined and Shiny and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Marble vs Coal. The hardness of Marble is 3-4 and that of Coal is 1-1.5. The types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble 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 Marble is white while that of Coal is black. The specific heat capacity of Marble is 0.88 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.Marble is heat resistant whereas Coal is heat resistant.
