Formation

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.
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Pyrolite and Comendite

Here you can know more about Pyrolite and Comendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Comendite 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 Comendite includes Albite, Amphibole, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Pyrolite vs Comendite, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Comendite is available in blue, bluish - grey colors. Appearance of Pyrolite is Rough and Shiny and that of Comendite is Foliated. Properties of rock is another aspect for Pyrolite vs Comendite. The hardness of Pyrolite is 5.5-6 and that of Comendite is 6-7. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite whereas types of Comendite are Rhyolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pyrolite is white while that of Comendite is bluish black. The specific heat capacity of Pyrolite is 1.25 kJ/Kg K and that of Comendite is 0.79 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 Comendite is heat resistant, impact resistant.
