Archaeological Significance
Formation
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Turbidite 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. Turbidite vs Scoria characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Turbidite and Properties of Scoria. Learn more about Turbidite vs Scoria in the next section. The interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Scoria include Decorative aggregates and Interior decoration. Due to some exceptional properties of Turbidite and Scoria, they have various applications in construction industry. The uses of Turbidite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement and that of Scoria include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works.
More about Turbidite and Scoria
Here you can know more about Turbidite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Scoria consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand 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 Sedimentary Rocks. When we have to compare Turbidite vs Scoria, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, green, grey, pink colors whereas, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Turbidite is Dull and Banded and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Turbidite vs Scoria. The hardness of Turbidite is 3 and that of Scoria is 5-6. The types of Turbidite are Sedimentary rock 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 Turbidite and Scoria is white, greenish white or grey. The specific heat capacity of Turbidite 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.Turbidite is heat resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
