Archaeological Significance
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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Gritstone vs Boninite 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 Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gritstone and Properties of Boninite. Learn more about Gritstone vs Boninite in the next section. The interior uses of Gritstone include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Gritstone and Boninite, they have various applications in construction industry. The uses of Gritstone in construction industry include Construction aggregate, Roadstone and that of Boninite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Gritstone and Boninite
Here you can know more about Gritstone and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Boninite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Sedimentary Rocks. When we have to compare Gritstone vs Boninite, the texture, color and appearance plays an important role in determining the type of rock. Gritstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Gritstone is Layered and Foliated and that of Boninite is Dull and Soft. Properties of rock is another aspect for Gritstone vs Boninite. The hardness of Gritstone is 6-7 and that of Boninite is 7. The types of Gritstone are Sedimentary rock whereas types of Boninite are Basalt. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gritstone and Boninite is white. The specific heat capacity of Gritstone is 0.92 kJ/Kg K and that of Boninite is 0.84 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 Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
