Formation
Sovites are formed due to low degrees of partial melting of rocks.
  
Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye.

Sovite vs Porphyry 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. Sovite vs Porphyry characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Sovite and Properties of Porphyry. Learn more about Sovite vs Porphyry in the next section. The interior uses of Sovite include Decorative aggregates and Homes whereas the interior uses of Porphyry include Decorative aggregates and Interior decoration. Due to some exceptional properties of Sovite and Porphyry, they have various applications in construction industry. The uses of Sovite in construction industry 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 and that of Porphyry include Construction aggregate.
More about Sovite and Porphyry
Here you can know more about Sovite and Porphyry. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Sovite and Porphyry consists of mineral content and compound content. The mineral content of Sovite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Porphyry includes Biotite, Chert, Feldspar, Garnet, Graphite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Sovite vs Porphyry, the texture, color and appearance plays an important role in determining the type of rock. Sovite is available in black, brown, colourless, green, grey, pink, white colors whereas, Porphyry is available in black, brown, colourless, green, grey, red, rust, white colors. Appearance of Sovite is Dull, Banded and Foilated and that of Porphyry is Dull. Properties of rock is another aspect for Sovite vs Porphyry. The hardness of Sovite is 3 and that of Porphyry is 6-7. The types of Sovite are Not Available whereas types of Porphyry are Rhomb Porphyry. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Sovite and Porphyry is white. The specific heat capacity of Sovite is Not Available and that of Porphyry is Not Available. 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 Porphyry is heat resistant, impact resistant.
