Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

Limestone vs Dacite 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 Dacite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Dacite. Learn more about Limestone vs Dacite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Limestone and Dacite, 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 Dacite include As dimension stone, Construction aggregate, For road aggregate, Landscaping.
More about Limestone and Dacite
Here you can know more about Limestone and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Dacite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all . When we have to compare Limestone vs Dacite, 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, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Limestone is Rough and Banded and that of Dacite is Vesicular. Properties of rock is another aspect for Limestone vs Dacite. The hardness of Limestone is 3-4 and that of Dacite is 2-2.25. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone and Dacite is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Dacite 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.Limestone is pressure resistant whereas Dacite is heat resistant, impact resistant, pressure resistant, wear resistant.
