Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Scoria vs Suevite 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. Scoria vs Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Suevite. Learn more about Scoria vs Suevite in the next section. The interior uses of Scoria include Decorative aggregates and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Scoria and Suevite, they have various applications in construction industry. The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Scoria and Suevite
Here you can know more about Scoria and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Suevite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Igneous Rocks. When we have to compare Scoria vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Suevite is available in black, brown, green, grey, pink colors. Appearance of Scoria is Glassy and Vesicular and that of Suevite is Banded. Properties of rock is another aspect for Scoria vs Suevite. The hardness of Scoria is 5-6 and that of Suevite is 5.5. The types of Scoria are Basaltic Scoria and Andesitic Scoria whereas types of Suevite are Phyllosilicates, Calcite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria is white while that of Suevite is light to dark brown. The specific heat capacity of Scoria is 0.84 kJ/Kg K and that of Suevite 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.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Suevite is heat resistant.
