Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
  
Theralite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Basanite vs Theralite 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. Basanite vs Theralite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Theralite. Learn more about Basanite vs Theralite in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Theralite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Basanite and Theralite, they have various applications in construction industry. The uses of Basanite in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Theralite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Basanite and Theralite
Here you can know more about Basanite and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Theralite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Theralite, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Theralite is available in dark grey to black colors. Appearance of Basanite is Glassy or Pearly and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Basanite vs Theralite. Hardness of Basanite and Theralite is 7. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Theralite are Teschenite and Essexite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite and Theralite is white. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Theralite 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.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Theralite is impact resistant, pressure resistant, wear resistant.
