Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite 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

Formation
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
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.

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. Suevite vs Hornfels characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Suevite and Properties of Hornfels. Learn more about Suevite vs Hornfels in the next section. The interior uses of Suevite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Hornfels include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Suevite and Hornfels, they have various applications in construction industry. The uses of Suevite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Hornfels include For road aggregate, Roadstone.
More about Suevite and Hornfels
Here you can know more about Suevite and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Hornfels consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite and mineral content of Hornfels includes Andalusite. You can also check out the list of all Metamorphic Rocks. When we have to compare Suevite vs Hornfels, the texture, color and appearance plays an important role in determining the type of rock. Suevite is available in black, brown, colourless, green, grey, pink colors whereas, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Suevite is Banded and that of Hornfels is Dull. Properties of rock is another aspect for Suevite vs Hornfels. The hardness of Suevite is 5.5 and that of Hornfels is 2-3. The types of Suevite are Phyllosilicates, Calcite 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 Suevite is light to dark brown while that of Hornfels is unknown. The specific heat capacity of Suevite is 0.92 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.Suevite is heat resistant whereas Hornfels is heat resistant, impact resistant, pressure resistant.
