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
Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Diamictite vs Chalk 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 Chalk characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Chalk. Learn more about Diamictite vs Chalk in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Chalk include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Diamictite and Chalk, 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 Chalk include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for manufacture of quicklime and slaked lime, Source of calcium.
More about Diamictite and Chalk
Here you can know more about Diamictite and Chalk. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Chalk consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Chalk, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Chalk is available in grey, white, yellow colors. Appearance of Diamictite is Banded and that of Chalk is Soft. Properties of rock is another aspect for Diamictite vs Chalk. The hardness of Diamictite is 2-3 and that of Chalk is 1. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Chalk are Not Available. 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 Chalk is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Chalk is 0.90 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 Chalk is heat resistant.
