Formation
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.
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.

Diatomite vs Gritstone 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. Diatomite vs Gritstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diatomite and Properties of Gritstone. Learn more about Diatomite vs Gritstone in the next section. The interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Gritstone include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Diatomite and Gritstone, they have various applications in construction industry. The uses of Diatomite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Source of calcium and that of Gritstone include Construction aggregate, Roadstone.
More about Diatomite and Gritstone
Here you can know more about Diatomite and Gritstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Gritstone consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Gritstone, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Diatomite is Soft and that of Gritstone is Layered and Foliated. Properties of rock is another aspect for Diatomite vs Gritstone. The hardness of Diatomite is 1 and that of Gritstone is 6-7. The types of Diatomite are Not Available whereas types of Gritstone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diatomite and Gritstone is white. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Gritstone is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diatomite is heat resistant whereas Gritstone is heat resistant, impact resistant, pressure resistant.
