Formation
Rhyodacite 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.

More about Rhyodacite and Sovite
Here you can know more about Rhyodacite and Sovite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhyodacite and Sovite consists of mineral content and compound content. The mineral content of Rhyodacite 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 Rhyodacite vs Sovite, the texture, color and appearance plays an important role in determining the type of rock. Rhyodacite is available in black to grey, dark greenish - grey colors whereas, Sovite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Rhyodacite is Skeletal and that of Sovite is Dull, Banded and Foilated. Properties of rock is another aspect for Rhyodacite vs Sovite. The hardness of Rhyodacite is 5.5-6 and that of Sovite is 3. The types of Rhyodacite are Not Available 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 Rhyodacite is black while that of Sovite is white. The specific heat capacity of Rhyodacite is 1.12 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.Rhyodacite is heat resistant whereas Sovite is heat resistant, pressure resistant.
