Definition
Gritstone or grit is a hard, coarse-grained, siliceous sandstone   
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Formation

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.   
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Gritstone vs Adakite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Gritstone and Adakite Reserves. Gritstone or grit is a hard, coarse-grained, siliceous sandstone. Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Gritstone vs Adakite information and Gritstone vs Adakite characteristics in the upcoming sections.

Gritstone vs Adakite 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 Adakite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gritstone and Properties of Adakite. Learn more about Gritstone vs Adakite in the next section. The interior uses of Gritstone include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Adakite include Decorative aggregates, Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Gritstone and Adakite, they have various applications in construction industry. The uses of Gritstone in construction industry include Construction aggregate, Roadstone and that of Adakite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Gritstone and Adakite

Here you can know more about Gritstone and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Adakite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Gritstone vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Gritstone is Layered and Foliated and that of Adakite is Dull and Soft. Properties of rock is another aspect for Gritstone vs Adakite. The hardness of Gritstone is 6-7 and that of Adakite is 3-4. The types of Gritstone are Not Available whereas types of Adakite are Not Available. 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 Adakite is bluish black. The specific heat capacity of Gritstone is 0.92 kJ/Kg K and that of Adakite is Not Available. 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 Adakite is heat resistant, pressure resistant, wear resistant.
