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
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Diamictite vs Shale 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 Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Shale. Learn more about Diamictite vs Shale in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Shale include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Diamictite and Shale, 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 Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Diamictite and Shale
Here you can know more about Diamictite and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Shale consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Shale, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Diamictite is Banded and that of Shale is Muddy. Properties of rock is another aspect for Diamictite vs Shale. The hardness of Diamictite is 2-3 and that of Shale is 3. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. 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 Shale is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Shale is 0.39 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 Shale is heat resistant, impact resistant.
