Definition
Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities

Features
Is one of the oldest rock, Typically speckled black and white.
Available in Lots of Colors and Patterns, Generally rough to touch, Surfaces are often shiny
Archaeological Significance
Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Tonalite vs Scoria 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 Scoria characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tonalite and Properties of Scoria. Learn more about Tonalite vs Scoria in the next section. The interior uses of Tonalite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Scoria include Decorative aggregates and Interior decoration. Due to some exceptional properties of Tonalite and Scoria, 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 Scoria include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works.
More about Tonalite and Scoria
Here you can know more about Tonalite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Scoria 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 Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Tonalite vs Scoria, 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, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Tonalite is Banded and Foilated and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Tonalite vs Scoria. The hardness of Tonalite is 6-7 and that of Scoria is 5-6. The types of Tonalite are Dacite whereas types of Scoria are Basaltic Scoria and Andesitic Scoria. 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 Scoria is white. The specific heat capacity of Tonalite is 0.92 kJ/Kg K and that of Scoria 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 Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
