Formation
Pyrolite 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 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.

Pyrolite vs Granulite 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. Pyrolite vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyrolite and Properties of Granulite. Learn more about Pyrolite vs Granulite in the next section. The interior uses of Pyrolite include Decorative aggregates and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Pyrolite and Granulite, they have various applications in construction industry. The uses of Pyrolite in construction industry include As dimension stone, Cobblestones and that of Granulite include As dimension stone, Building houses or walls.
More about Pyrolite and Granulite
Here you can know more about Pyrolite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Granulite consists of mineral content and compound content. The mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Pyrolite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Granulite is available in black, brown colors. Appearance of Pyrolite is Rough and Shiny and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Pyrolite vs Granulite. The hardness of Pyrolite is 5.5-6 and that of Granulite is 6-7. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pyrolite and Granulite is white. The specific heat capacity of Pyrolite is 1.25 kJ/Kg K and that of Granulite is 0.14 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Granulite is heat resistant, wear resistant.
