Formation
Picrite 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.
Sovites are formed due to low degrees of partial melting of rocks.

Picrite vs Sovite 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. Picrite vs Sovite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Picrite and Properties of Sovite. Learn more about Picrite vs Sovite in the next section. The interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Sovite include Decorative aggregates and Homes. Due to some exceptional properties of Picrite and Sovite, they have various applications in construction industry. The uses of Picrite in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills. and that of Sovite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Unknown, Unknown.
More about Picrite and Sovite
Here you can know more about Picrite and Sovite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Picrite and Sovite consists of mineral content and compound content. The mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite and mineral content of Sovite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Picrite vs Sovite, the texture, color and appearance plays an important role in determining the type of rock. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas, Sovite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Picrite is Rough and Shiny and that of Sovite is Dull, Banded and Foilated. Properties of rock is another aspect for Picrite vs Sovite. The hardness of Picrite is 6.8 and that of Sovite is 3. The types of Picrite are Oceanite whereas types of Sovite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Picrite and Sovite is white, greenish white or grey. The specific heat capacity of Picrite is 0.88 kJ/Kg K and that of Sovite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Picrite is heat resistant whereas Sovite is heat resistant, pressure resistant.
