Formation

Latite 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.

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

More about Latite and Dunite

Here you can know more about Latite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Dunite consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Dunite, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, green, grey, pink, white colors whereas, Dunite is available in dark greenish - grey colors. Appearance of Latite is Rough and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Latite vs Dunite. The hardness of Latite is 5-5.5 and that of Dunite is 3.5-4. The types of Latite are Rhomb porphyries whereas types of Dunite are Dunite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite and Dunite is white. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Dunite is 1.25 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Latite is heat resistant, pressure resistant whereas Dunite is heat resistant, pressure resistant, wear resistant.
