More about Tonalite and Dunite

Here you can know more about Tonalite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Dunite 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 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 Tonalite vs Dunite, 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, Dunite is available in dark greenish - grey colors. Appearance of Tonalite is Banded and Foilated and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Tonalite vs Dunite. The hardness of Tonalite is 6-7 and that of Dunite is 3.5-4. The types of Tonalite are Dacite whereas types of Dunite 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 Dunite is white.
