Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

Tonalite vs Amphibolite 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 Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tonalite and Properties of Amphibolite. Learn more about Tonalite vs Amphibolite in the next section. The interior uses of Tonalite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Tonalite and Amphibolite, 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 Amphibolite include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone.
More about Tonalite and Amphibolite
Here you can know more about Tonalite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Amphibolite 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 Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Tonalite vs Amphibolite, 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, Amphibolite is available in black, brown, green, grey colors. Appearance of Tonalite is Banded and Foilated and that of Amphibolite is Foliated. Properties of rock is another aspect for Tonalite vs Amphibolite. Hardness of Tonalite and Amphibolite is 6-7. The types of Tonalite are Dacite whereas types of Amphibolite are Hornblendite. 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 Amphibolite is white to grey. The specific heat capacity of Tonalite is 0.92 kJ/Kg K and that of Amphibolite 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 Amphibolite is heat resistant, pressure resistant, wear resistant.
