Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Foidolites 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 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.

Foidolite vs Suevite 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. Foidolite vs Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Foidolite and Properties of Suevite. Learn more about Foidolite vs Suevite in the next section. The interior uses of Foidolite include Decorative aggregates and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Foidolite and Suevite, they have various applications in construction industry. The uses of Foidolite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Foidolite and Suevite
Here you can know more about Foidolite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Suevite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, green, grey, pink, white colors whereas, Suevite is available in black, brown, green, grey, pink colors. Appearance of Foidolite is Dull and that of Suevite is Banded. Properties of rock is another aspect for Foidolite vs Suevite. The hardness of Foidolite is 1.5 and that of Suevite is 5.5. The types of Foidolite are Igneous rock whereas types of Suevite are Phyllosilicates, Calcite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Foidolite is white while that of Suevite is light to dark brown. The specific heat capacity of Foidolite is 0.79 kJ/Kg K and that of Suevite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Foidolite is heat resistant, wear resistant whereas Suevite is heat resistant.
