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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Dacite vs Laterite 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 Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dacite and Properties of Laterite. Learn more about Dacite vs Laterite in the next section. The interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Dacite and Laterite, 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 Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Dacite and Laterite
Here you can know more about Dacite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Laterite 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 Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Dacite vs Laterite, 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, Laterite is available in brown, buff, red colors. Appearance of Dacite is Vesicular and that of Laterite is Rough and Banded. Properties of rock is another aspect for Dacite vs Laterite. The hardness of Dacite is 2-2.25 and that of Laterite is 2. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite whereas types of Laterite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dacite and Laterite is white. The specific heat capacity of Dacite is 0.92 kJ/Kg K and that of Laterite is Not Available. 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 Laterite is heat resistant, pressure resistant.
