Archaeological Significance
Formation
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
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.

Turbidite 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. Turbidite vs Chert characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Turbidite and Properties of Chert. Learn more about Turbidite vs Chert in the next section. The interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Chert include Decorative aggregates and Homes. Due to some exceptional properties of Turbidite and Chert, they have various applications in construction industry. The uses of Turbidite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement and that of Chert include Arrowheads, Construction aggregate, Cutting tool, Spear points.
More about Turbidite and Chert
Here you can know more about Turbidite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Chert consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Chert includes Quartz, Silicon. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Chert, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, green, grey, pink colors whereas, Chert is available in black, brown, green, grey, red, white colors. Appearance of Turbidite is Dull and Banded and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Turbidite vs Chert. The hardness of Turbidite is 3 and that of Chert is 6.5-7. The types of Turbidite are Sedimentary rock 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 Turbidite and Chert is white, greenish white or grey. The specific heat capacity of Turbidite 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.Turbidite is heat resistant whereas Chert is heat resistant, impact resistant, pressure resistant, wear resistant.
