1 Definition

1.1 Definition

Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture

Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

5 Formation

5.1 Formation

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

Tachylite 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.

Tonalite vs Tachylite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Tonalite and Tachylite Reserves. Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes.

More about Tonalite and Tachylite

Here you can know more about Tonalite and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Tachylite 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 Tachylite includes Feldspar, Olivine. You can also check out the list of all Igneous Rocks. When we have to compare Tonalite vs Tachylite, 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, Tachylite is available in black, dark brown colors. Appearance of Tonalite is Banded and Foilated and that of Tachylite is Glassy. Properties of rock is another aspect for Tonalite vs Tachylite. The hardness of Tonalite is 6-7 and that of Tachylite is 5.5. The types of Tonalite are Dacite whereas types of Tachylite 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 Tachylite is vermilion. The specific heat capacity of Tonalite is 0.92 kJ/Kg K and that of Tachylite is 0.56 kJ/Kg K.
