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
Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

Diamictite vs Chert 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 Chert characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Chert. Learn more about Diamictite vs Chert in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Chert include Decorative aggregates and Homes. Due to some exceptional properties of Diamictite and Chert, 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 Chert include Arrowheads, Construction aggregate, Cutting tool, Spear points.
More about Diamictite and Chert
Here you can know more about Diamictite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Chert consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Chert includes Quartz, Silicon. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Chert, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Chert is available in black, brown, green, grey, red, white colors. Appearance of Diamictite is Banded and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Diamictite vs Chert. The hardness of Diamictite is 2-3 and that of Chert is 6.5-7. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter. 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 Chert is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Chert is 0.74 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 Chert is heat resistant, impact resistant, pressure resistant, wear resistant.
