Formation
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.
  
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Rhyolite 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. Rhyolite vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Rhyolite and Properties of Laterite. Learn more about Rhyolite vs Laterite in the next section. The interior uses of Rhyolite include Decorative aggregates, Homes, Hotels, Interior decoration and Kitchens whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Rhyolite and Laterite, they have various applications in construction industry. The uses of Rhyolite in construction industry include Arrowheads, As dimension stone, Building houses or walls, Construction aggregate, Cutting tool, For road aggregate, Knives and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Rhyolite and Laterite
Here you can know more about Rhyolite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhyolite and Laterite consists of mineral content and compound content. The mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz 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 Rhyolite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Rhyolite is available in grey, white, light black colors whereas, Laterite is available in brown, buff, red colors. Appearance of Rhyolite is Banded and that of Laterite is Rough and Banded. Properties of rock is another aspect for Rhyolite vs Laterite. The hardness of Rhyolite is 6-7 and that of Laterite is 2. The types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks. 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 Rhyolite is colorless while that of Laterite is white. The specific heat capacity of Rhyolite is Not Available 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.Rhyolite is heat resistant, wear resistant whereas Laterite is heat resistant, pressure resistant.
