Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
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.

Appinite 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. Appinite vs Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Appinite and Properties of Suevite. Learn more about Appinite vs Suevite in the next section. The interior uses of Appinite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Appinite and Suevite, they have various applications in construction industry. The uses of Appinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Appinite and Suevite
Here you can know more about Appinite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Suevite consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, 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 Appinite vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Suevite is available in black, brown, green, grey, pink colors. Appearance of Appinite is Dull, Banded and Foilated and that of Suevite is Banded. Properties of rock is another aspect for Appinite vs Suevite. The hardness of Appinite is 5-6 and that of Suevite is 5.5. The types of Appinite 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 Appinite is white while that of Suevite is light to dark brown. The specific heat capacity of Appinite is 0.84 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.Appinite is heat resistant, impact resistant whereas Suevite is heat resistant.
