Definition
Mangerite is a plutonic intrusive igneous rock, which is essentially a hypersthene-bearing monzonite
Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth

Formation
Mangerite 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.
When the lava is released from volcano, it undergoes a very rapid cooling which freezes the mechanisms of crystallization. The result is a volcanic glass with a uniform smooth texture.

More about Mangerite and Obsidian
Here you can know more about Mangerite and Obsidian. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mangerite and Obsidian consists of mineral content and compound content. The mineral content of Mangerite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Obsidian is not available. You can also check out the list of all Igneous Rocks. When we have to compare Mangerite vs Obsidian, the texture, color and appearance plays an important role in determining the type of rock. Mangerite is available in black, brown, light to dark grey, white colors whereas, Obsidian is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Mangerite is Shiny and that of Obsidian is Shiny. Properties of rock is another aspect for Mangerite vs Obsidian. The hardness of Mangerite is 6-7 and that of Obsidian is 5-5.5. The types of Mangerite are Not Available whereas types of Obsidian are Fireworks Obsidian, Mahogany, Sheen Obsidian, Snowflake obsidian and Velvet Peacock Obsidian. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mangerite and Obsidian is white. The specific heat capacity of Mangerite is 0.92 kJ/Kg K and that of Obsidian is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mangerite is heat resistant, impact resistant, pressure resistant whereas Obsidian is heat resistant, impact resistant.
