Definition
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded
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
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
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.

Sandstone 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. Sandstone vs Adakite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Sandstone and Properties of Adakite. Learn more about Sandstone vs Adakite in the next section. The interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration whereas the interior uses of Adakite include Decorative aggregates, Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Sandstone and Adakite, 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 Adakite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Sandstone and Adakite
Here you can know more about Sandstone and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Sandstone and Adakite consists of mineral content and compound content. The mineral content of Sandstone includes Calcite, Clay, 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 Sandstone vs Adakite, the texture, color and appearance plays an important role in determining the type of rock. Sandstone is available in beige, black, brown, 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 Sandstone is Rough and that of Adakite is Dull and Soft. Properties of rock is another aspect for Sandstone vs Adakite. The hardness of Sandstone is 6-7 and that of Adakite is 3-4. The types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister whereas types of Adakite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Sandstone is white while that of Adakite is bluish black. The specific heat capacity of Sandstone is 0.92 kJ/Kg K and that of Adakite 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.Sandstone is heat resistant, impact resistant, pressure resistant whereas Adakite is heat resistant, pressure resistant, wear resistant.
