Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

More about Tonalite and Laterite
Here you can know more about Tonalite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Laterite consists of mineral content and compound content. The mineral content of Tonalite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, 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 Tonalite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Tonalite is available in black, brown, light to dark grey, white colors whereas, Laterite is available in brown, buff, red colors. Appearance of Tonalite is Banded and Foilated and that of Laterite is Rough and Banded. Properties of rock is another aspect for Tonalite vs Laterite. The hardness of Tonalite is 6-7 and that of Laterite is 2. The types of Tonalite are 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 Tonalite is bluish black while that of Laterite is white. The specific heat capacity of Tonalite 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.Tonalite is heat resistant, pressure resistant, water resistant whereas Laterite is heat resistant, pressure resistant.
