Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Rhyodacite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Laterite and Rhyodacite
Here you can know more about Laterite and Rhyodacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Rhyodacite 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 Rhyodacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Rhyodacite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Rhyodacite is available in black to grey, dark greenish - grey colors. Appearance of Laterite is Rough and Banded and that of Rhyodacite is Skeletal. Properties of rock is another aspect for Laterite vs Rhyodacite.
