Features
Available in lots of colors, Generally rough to touch, Is one of the oldest rock
Very fine grained rock, It is One of the Oldest, Strongest and Hardest Rock
Archaeological Significance
Formation
Sovites are formed due to low degrees of partial melting of 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 Sovite and Comendite
Here you can know more about Sovite and Comendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Sovite and Comendite consists of mineral content and compound content. The mineral content of Sovite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite 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 Sovite vs Comendite, the texture, color and appearance plays an important role in determining the type of rock. Sovite is available in black, brown, green, grey, pink, white colors whereas, Comendite is available in blue, bluish - grey colors. Appearance of Sovite is Dull, Banded and Foilated and that of Comendite is Foliated. Properties of rock is another aspect for Sovite vs Comendite. The hardness of Sovite is 3 and that of Comendite is 6-7. The types of Sovite are Carbonatite 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 Sovite is white while that of Comendite is bluish black. The specific heat capacity of Sovite is 0.84 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.Sovite is heat resistant, pressure resistant whereas Comendite is heat resistant, impact resistant.
