Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Troctolite 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 Troctolite
Here you can know more about Laterite and Troctolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Troctolite 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 Troctolite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Troctolite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Troctolite is available in dark grey to black colors. Appearance of Laterite is Rough and Banded and that of Troctolite is Veined and Shiny. Properties of rock is another aspect for Laterite vs Troctolite. The hardness of Laterite is 2 and that of Troctolite is 7. The types of Laterite are Not Available whereas types of Troctolite are Not Available. 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 Troctolite is black. The specific heat capacity of Laterite is Not Available and that of Troctolite is Not Available. 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 Troctolite is impact resistant, pressure resistant, wear resistant.
