Formation

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

Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

More about Laterite and Rhyolite

Here you can know more about Laterite and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Rhyolite consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene and mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Rhyolite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Rhyolite is available in grey, white, light black colors. Appearance of Laterite is Rough and Banded and that of Rhyolite is Banded. Properties of rock is another aspect for Laterite vs Rhyolite. The hardness of Laterite is 2 and that of Rhyolite is 6-7. The types of Laterite are Laterite whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite is white while that of Rhyolite is . The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Rhyolite is 0.71 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Laterite is heat resistant, pressure resistant whereas Rhyolite is heat resistant, wear resistant.
