Diamictite vs Coal


Definition

Definition
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds   
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

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.   
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Coal vs Diamictite 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 Diamictite Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone. 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 Diamictite information and Coal vs Diamictite characteristics in the upcoming sections.

Coal vs Diamictite 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 Diamictite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Diamictite. Learn more about Coal vs Diamictite in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Diamictite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Coal and Diamictite, 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 Diamictite include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone.

More about Coal and Diamictite

Here you can know more about Coal and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Diamictite 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 Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Diamictite, 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, Diamictite is available in brown, buff colors. Appearance of Coal is Veined or Pebbled and that of Diamictite is Banded. Properties of rock is another aspect for Coal vs Diamictite. The hardness of Coal is 1-1.5 and that of Diamictite is 2-3. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. 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 Diamictite is light to dark brown. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Diamictite is 0.75 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 Diamictite is heat resistant, impact resistant.
