Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Variolites are a group of dark green basic igneous rocks which exhibit pale colored spots, or spherules, especially on weathered surfaces, that give them a pockmarked appearance

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.
Variolites are a group of dark green basic igneous rocks that exhibit pale colored spots on weathered surfaces that give them a pockmarked appearance.

Suevite vs Variolite 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. Suevite vs Variolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Suevite and Properties of Variolite. Learn more about Suevite vs Variolite in the next section. The interior uses of Suevite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Variolite include Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Suevite and Variolite, 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 Variolite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Suevite and Variolite
Here you can know more about Suevite and Variolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Variolite consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite and mineral content of Variolite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Suevite vs Variolite, 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, Variolite is available in black, brown, light to dark grey colors. Appearance of Suevite is Banded and that of Variolite is Dull and Soft. Properties of rock is another aspect for Suevite vs Variolite. The hardness of Suevite is 5.5 and that of Variolite is 6. The types of Suevite are Phyllosilicates, Calcite whereas types of Variolite are Not Available. 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 Variolite is white to grey. The specific heat capacity of Suevite is 0.92 kJ/Kg K and that of Variolite 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 Variolite is heat resistant, pressure resistant, wear resistant.
