Definition
Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

Tonalite vs Ganister 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 Ganister characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tonalite and Properties of Ganister. Learn more about Tonalite vs Ganister in the next section. The interior uses of Tonalite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Ganister include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Tonalite and Ganister, 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 Ganister include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Tonalite and Ganister
Here you can know more about Tonalite and Ganister. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Ganister 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 Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tonalite vs Ganister, 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, Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Tonalite is Banded and Foilated and that of Ganister is Rough. Properties of rock is another aspect for Tonalite vs Ganister. Hardness of Tonalite and Ganister is 6-7. The types of Tonalite are Dacite whereas types of Ganister 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 Ganister is white. The specific heat capacity of Tonalite is 0.92 kJ/Kg K and that of Ganister is 0.92 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 Ganister is heat resistant, impact resistant, pressure resistant.
