Formation
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Gritstone 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. Gritstone vs Diamictite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gritstone and Properties of Diamictite. Learn more about Gritstone vs Diamictite in the next section. The interior uses of Gritstone include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Diamictite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Gritstone and Diamictite, they have various applications in construction industry. The uses of Gritstone in construction industry include Construction aggregate, Roadstone and that of Diamictite include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone.
More about Gritstone and Diamictite
Here you can know more about Gritstone and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Diamictite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz 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 Gritstone vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Diamictite is available in brown, buff colors. Appearance of Gritstone is Layered and Foliated and that of Diamictite is Banded. Properties of rock is another aspect for Gritstone vs Diamictite. The hardness of Gritstone is 6-7 and that of Diamictite is 2-3. The types of Gritstone are Not Available 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 Gritstone is white while that of Diamictite is light to dark brown. The specific heat capacity of Gritstone is 0.92 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.Gritstone is heat resistant, impact resistant, pressure resistant whereas Diamictite is heat resistant, impact resistant.
