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.
Picrite 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.

Suevite vs Picrite 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 Picrite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Suevite and Properties of Picrite. Learn more about Suevite vs Picrite in the next section. The interior uses of Suevite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Suevite and Picrite, 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 Picrite include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills..
More about Suevite and Picrite
Here you can know more about Suevite and Picrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Picrite consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite and mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite. You can also check out the list of all Metamorphic Rocks. When we have to compare Suevite vs Picrite, the texture, color and appearance plays an important role in determining the type of rock. Suevite is available in black, brown, green, grey, pink colors whereas, Picrite is available in black, brown, green, grey, pink, white, yellow colors. Appearance of Suevite is Banded and that of Picrite is Rough and Shiny. Properties of rock is another aspect for Suevite vs Picrite. The hardness of Suevite is 5.5 and that of Picrite is 6.8. The types of Suevite are Phyllosilicates, Calcite whereas types of Picrite are Oceanite. 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 Picrite is white, greenish white or grey. The specific heat capacity of Suevite is 0.92 kJ/Kg K and that of Picrite is 0.88 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 Picrite is heat resistant.
