Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
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
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
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.

Limestone 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. Limestone vs Adakite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Adakite. Learn more about Limestone vs Adakite in the next section. The interior uses of Limestone include 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 Limestone and Adakite, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Adakite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Limestone and Adakite
Here you can know more about Limestone and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Adakite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt 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 Limestone vs Adakite, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Adakite is available in black, brown, light to dark grey colors. Appearance of Limestone is Rough and Banded and that of Adakite is Dull and Soft. Properties of rock is another aspect for Limestone vs Adakite. Hardness of Limestone and Adakite is 3-4. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa 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 Limestone is white while that of Adakite is bluish black. The specific heat capacity of Limestone is 0.91 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.Limestone is pressure resistant whereas Adakite is heat resistant, pressure resistant, wear resistant.
