Definition
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time
Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt

Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
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.

Marble vs Pyrolite 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. Marble vs Pyrolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Marble and Properties of Pyrolite. Learn more about Marble vs Pyrolite in the next section. The interior uses of Marble include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Pyrolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Marble and Pyrolite, they have various applications in construction industry. The uses of Marble in construction industry include As dimension stone and that of Pyrolite include As dimension stone, Cobblestones.
More about Marble and Pyrolite
Here you can know more about Marble and Pyrolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marble and Pyrolite consists of mineral content and compound content. The mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz and mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Marble vs Pyrolite, the texture, color and appearance plays an important role in determining the type of rock. Marble is available in black, blue, brown, grey, pink, white colors whereas, Pyrolite is available in dark greenish - grey colors. Appearance of Marble is Veined and Shiny and that of Pyrolite is Rough and Shiny. Properties of rock is another aspect for Marble vs Pyrolite. The hardness of Marble is 3-4 and that of Pyrolite is 5.5-6. The types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble whereas types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marble and Pyrolite is white. The specific heat capacity of Marble is 0.88 kJ/Kg K and that of Pyrolite is 1.25 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Marble is heat resistant whereas Pyrolite is heat resistant, pressure resistant, wear resistant.
