Definition
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock
Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock

Archaeological Significance
Formation
Sovites are formed due to low degrees of partial melting of rocks.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Hornfels is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Sovite and Hornfels
Here you can know more about Sovite and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Sovite and Hornfels consists of mineral content and compound content. The mineral content of Sovite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Hornfels includes Andalusite. You can also check out the list of all Igneous Rocks. When we have to compare Sovite vs Hornfels, 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, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Sovite is Dull, Banded and Foilated and that of Hornfels is Dull. Properties of rock is another aspect for Sovite vs Hornfels. The hardness of Sovite is 3 and that of Hornfels is 2-3. The types of Sovite are Carbonatite whereas types of Hornfels are Biotite hornfels. 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 Hornfels is . The specific heat capacity of Sovite is 0.84 kJ/Kg K and that of Hornfels 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.Sovite is heat resistant, pressure resistant whereas Hornfels is heat resistant, impact resistant, pressure resistant.
