Definition

Definition

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

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

Shale 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 Shale and Diamictite Reserves. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. 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 Shale vs Diamictite information and Shale vs Diamictite characteristics in the upcoming sections.

Shale 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. Shale vs Diamictite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Diamictite. Learn more about Shale vs Diamictite in the next section. The interior uses of Shale include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Diamictite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Shale and Diamictite, they have various applications in construction industry. The uses of Shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Diamictite include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone.

More about Shale and Diamictite

Here you can know more about Shale and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Diamictite consists of mineral content and compound content. The mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides 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 Shale vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Diamictite is available in brown, buff colors. Appearance of Shale is Muddy and that of Diamictite is Banded. Properties of rock is another aspect for Shale vs Diamictite. The hardness of Shale is 3 and that of Diamictite is 2-3. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale 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 Shale is white while that of Diamictite is light to dark brown. The specific heat capacity of Shale is 0.39 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.Shale is heat resistant, impact resistant whereas Diamictite is heat resistant, impact resistant.
