Archaeological Significance
Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

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 Basanite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Basanite . Learn more about Scoria vs Basanite in the next section. The interior uses of Scoria include Decorative aggregates and Interior decoration whereas the interior uses of Basanite include Decorative aggregates and Homes. Due to some exceptional properties of Scoria and Basanite , 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 Basanite include Arrowheads, Construction aggregate, Cutting tool, Spear points.
More about Scoria and Basanite
Here you can know more about Scoria and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Basanite 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 Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Scoria vs Basanite , 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, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Scoria is Glassy and Vesicular and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Scoria vs Basanite . The hardness of Scoria is 5-6 and that of Basanite is 7. The types of Scoria are Basaltic Scoria and Andesitic Scoria whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria and Basanite is white. The specific heat capacity of Scoria is 0.84 kJ/Kg K and that of Basanite is 0.74 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 Basanite is heat resistant, impact resistant, pressure resistant, wear resistant.
