Archaeological Significance
Formation
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.
Sovites are formed due to low degrees of partial melting of rocks.

Dacite 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. Dacite vs Sovite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dacite and Properties of Sovite. Learn more about Dacite vs Sovite in the next section. The interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Sovite include Decorative aggregates and Homes. Due to some exceptional properties of Dacite and Sovite, they have various applications in construction industry. The uses of Dacite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping 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.
More about Dacite and Sovite
Here you can know more about Dacite and Sovite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Sovite consists of mineral content and compound content. The mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon 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 Dacite vs Sovite, the texture, color and appearance plays an important role in determining the type of rock. Dacite is available in bluish - grey, brown, grey, light to dark grey colors whereas, Sovite is available in black, brown, green, grey, pink, white colors. Appearance of Dacite is Vesicular and that of Sovite is Dull, Banded and Foilated. Properties of rock is another aspect for Dacite vs Sovite. The hardness of Dacite is 2-2.25 and that of Sovite is 3. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite whereas types of Sovite are Carbonatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dacite and Sovite is white. The specific heat capacity of Dacite is 0.92 kJ/Kg K and that of Sovite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dacite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Sovite is heat resistant, pressure resistant.
