Definition
Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Tonalite vs Boninite 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 Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tonalite and Properties of Boninite. Learn more about Tonalite vs Boninite in the next section. The interior uses of Tonalite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Tonalite and Boninite, 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 Boninite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Tonalite and Boninite
Here you can know more about Tonalite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Boninite 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 Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Tonalite vs Boninite, 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, Boninite is available in bluish - grey, brown, colourless, green, grey colors. Appearance of Tonalite is Banded and Foilated and that of Boninite is Dull and Soft. Properties of rock is another aspect for Tonalite vs Boninite. The hardness of Tonalite is 6-7 and that of Boninite is 7. The types of Tonalite are Dacite whereas types of Boninite 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 Boninite is white. The specific heat capacity of Tonalite is 0.92 kJ/Kg K and that of Boninite is Not Available. 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 Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
