5 Formation

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.

Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Chert vs Diamictite 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 Diamictite Reserves. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture. Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone. 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 Diamictite information and Chert vs Diamictite characteristics in the upcoming sections.

More about Chert and Diamictite

Here you can know more about Chert and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chert and Diamictite consists of mineral content and compound content. The mineral content of Chert includes Quartz, Silicon and mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Chert vs Diamictite, 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, Diamictite is available in brown, buff colors. Appearance of Chert is Glassy or Pearly and that of Diamictite is Banded. Properties of rock is another aspect for Chert vs Diamictite. The hardness of Chert is 6.5-7 and that of Diamictite is 2-3. The types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. 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 Diamictite is light to dark brown. The specific heat capacity of Chert is 0.74 kJ/Kg K and that of Diamictite is 0.75 kJ/Kg K.
