Formation
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
  
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

More about Diorite and Laterite
Here you can know more about Diorite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diorite and Laterite consists of mineral content and compound content. The mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, 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 Diorite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Diorite is available in black, brown, light to dark grey, white colors whereas, Laterite is available in brown, buff, red colors. Appearance of Diorite is Shiny and that of Laterite is Rough and Banded. Properties of rock is another aspect for Diorite vs Laterite. The hardness of Diorite is 6-7 and that of Laterite is 2. The types of Diorite are Not Available 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 Diorite is bluish black while that of Laterite is white. The specific heat capacity of Diorite 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.Diorite is heat resistant, pressure resistant, wear resistant whereas Laterite is heat resistant, pressure resistant.
