Archaeological Significance
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.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

Suevite vs Dacite 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 Dacite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Suevite and Properties of Dacite. Learn more about Suevite vs Dacite in the next section. The interior uses of Suevite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Suevite and Dacite, 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 Dacite include As dimension stone, Construction aggregate, For road aggregate, Landscaping.
More about Suevite and Dacite
Here you can know more about Suevite and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Dacite consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite and mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Suevite vs Dacite, 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, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Suevite is Banded and that of Dacite is Vesicular. Properties of rock is another aspect for Suevite vs Dacite. The hardness of Suevite is 5.5 and that of Dacite is 2-2.25. The types of Suevite are Phyllosilicates, Calcite whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite. 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 Dacite is white. The specific heat capacity of Suevite is 0.92 kJ/Kg K and that of Dacite 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.Suevite is heat resistant whereas Dacite is heat resistant, impact resistant, pressure resistant, wear resistant.
