Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
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.

Granulite 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. Granulite vs Theralite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Theralite. Learn more about Granulite vs Theralite in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Theralite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Granulite and Theralite, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Theralite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Granulite and Theralite
Here you can know more about Granulite and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Theralite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Theralite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Theralite is available in dark grey to black colors. Appearance of Granulite is Veined or Pebbled and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Granulite vs Theralite. The hardness of Granulite is 6-7 and that of Theralite is 7. The types of Granulite are Not Available 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 Granulite and Theralite is white. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Theralite is impact resistant, pressure resistant, wear resistant.
