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

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
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 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. Diamictite vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Coal. Learn more about Diamictite vs Coal in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Diamictite and Coal, they have various applications in construction industry. The uses of Diamictite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Diamictite and Coal
Here you can know more about Diamictite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Coal consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, 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 Sedimentary Rocks. When we have to compare Diamictite vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Diamictite is Banded and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Diamictite vs Coal. The hardness of Diamictite is 2-3 and that of Coal is 1-1.5. The types of Diamictite are Bedded Diamictite and Laminated Diamictite 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 Diamictite is light to dark brown while that of Coal is black. The specific heat capacity of Diamictite is 0.75 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.Diamictite is heat resistant, impact resistant whereas Coal is heat resistant.
