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.
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

Suevite vs Chert 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 Chert characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Suevite and Properties of Chert. Learn more about Suevite vs Chert in the next section. The interior uses of Suevite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Chert include Decorative aggregates and Homes. Due to some exceptional properties of Suevite and Chert, 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 Chert include Arrowheads, Construction aggregate, Cutting tool, Spear points.
More about Suevite and Chert
Here you can know more about Suevite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Chert consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite and mineral content of Chert includes Quartz, Silicon. You can also check out the list of all Metamorphic Rocks. When we have to compare Suevite vs Chert, 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, Chert is available in black, brown, green, grey, red, white colors. Appearance of Suevite is Banded and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Suevite vs Chert. The hardness of Suevite is 5.5 and that of Chert is 6.5-7. The types of Suevite are Phyllosilicates, Calcite whereas types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter. 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 Chert is white. The specific heat capacity of Suevite is 0.92 kJ/Kg K and that of Chert is 0.74 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 Chert is heat resistant, impact resistant, pressure resistant, wear resistant.
