Definition
Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

Archaeological Significance
Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Tonalite vs Granulite 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 Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tonalite and Properties of Granulite. Learn more about Tonalite vs Granulite in the next section. The interior uses of Tonalite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Tonalite and Granulite, 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 Granulite include As dimension stone, Building houses or walls.
More about Tonalite and Granulite
Here you can know more about Tonalite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Granulite 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 Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tonalite vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Tonalite is Banded and Foilated and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Tonalite vs Granulite. Hardness of Tonalite and Granulite is 6-7. The types of Tonalite are Dacite whereas types of Granulite are Metamorphic rock. 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 Granulite is white. The specific heat capacity of Tonalite is 0.92 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
