Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
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.

Sandstone 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. Sandstone vs Gritstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Sandstone and Properties of Gritstone. Learn more about Sandstone vs Gritstone in the next section. The interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration whereas the interior uses of Gritstone include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Sandstone and Gritstone, they have various applications in construction industry. The uses of Sandstone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Gritstone include Construction aggregate, Roadstone.
More about Sandstone and Gritstone
Here you can know more about Sandstone and Gritstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Sandstone and Gritstone consists of mineral content and compound content. The mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz 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 Sandstone vs Gritstone, the texture, color and appearance plays an important role in determining the type of rock. Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, 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 Sandstone is Rough and that of Gritstone is Layered and Foliated. Properties of rock is another aspect for Sandstone vs Gritstone. Hardness of Sandstone and Gritstone is 6-7. The types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister 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 Sandstone and Gritstone is white. The specific heat capacity of Sandstone is 0.92 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.Sandstone is heat resistant, impact resistant, pressure resistant whereas Gritstone is heat resistant, impact resistant, pressure resistant.
