1.1 Definition

Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture

During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

5.1 Formation

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 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 vs Suevite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Chert and Suevite Reserves. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture. During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Chert vs Suevite information and Chert vs Suevite characteristics in the upcoming sections.

Chert 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. Chert vs Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chert and Properties of Suevite. Learn more about Chert vs Suevite in the next section. The interior uses of Chert include Decorative aggregates and Homes whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Chert and Suevite, they have various applications in construction industry. The uses of Chert in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Chert and Suevite

Here you can know more about Chert and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chert and Suevite consists of mineral content and compound content. The mineral content of Chert includes Quartz, Silicon and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Sedimentary Rocks. When we have to compare Chert vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Chert is available in black, brown, green, grey, red, white colors whereas, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Chert is Glassy or Pearly and that of Suevite is Banded. Properties of rock is another aspect for Chert vs Suevite. The hardness of Chert is 6.5-7 and that of Suevite is 5.5. The types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter 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 Chert is white while that of Suevite is light to dark brown. The specific heat capacity of Chert is 0.74 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.Chert is heat resistant, impact resistant, pressure resistant, wear resistant whereas Suevite is heat resistant.
