Formation
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 is a sedimentary rock which is mainly made up of calcium carbonate.

Dacite vs Limestone 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. Dacite vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dacite and Properties of Limestone. Learn more about Dacite vs Limestone in the next section. The interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Dacite and Limestone, they have various applications in construction industry. The uses of Dacite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Dacite and Limestone
Here you can know more about Dacite and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Limestone consists of mineral content and compound content. The mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Dacite vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Dacite is available in bluish - grey, brown, grey, light to dark grey colors whereas, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Dacite is Vesicular and that of Limestone is Rough and Banded. Properties of rock is another aspect for Dacite vs Limestone. The hardness of Dacite is 2-2.25 and that of Limestone is 3-4. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dacite and Limestone is white. The specific heat capacity of Dacite is 0.92 kJ/Kg K and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dacite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Limestone is pressure resistant.
