Formation

Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.  
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Tonalite vs Charnockite 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 Charnockite Reserves. Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. 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. You can check out Tonalite vs Charnockite information and Tonalite vs Charnockite characteristics in the upcoming sections.

Tonalite vs Charnockite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Tonalite vs Charnockite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tonalite and Properties of Charnockite. Learn more about Tonalite vs Charnockite in the next section. The interior uses of Tonalite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Tonalite and Charnockite, they have various applications in construction industry. The uses of Tonalite in construction industry include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate and that of Charnockite include As dimension stone.

More about Tonalite and Charnockite

Here you can know more about Tonalite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Charnockite 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 Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tonalite vs Charnockite, 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, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Tonalite is Banded and Foilated and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Tonalite vs Charnockite. Hardness of Tonalite and Charnockite is 6-7. The types of Tonalite are Dacite whereas types of Charnockite are Enderbite. 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 Charnockite is white. The specific heat capacity of Tonalite is 0.92 kJ/Kg K and that of Charnockite is 0.84 kJ/Kg K. 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 Charnockite is heat resistant, wear resistant.
