5 Formation
5.1 Formation
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.
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.

Diatomite vs Chert 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 Diatomite and Chert Reserves. Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture. 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 Diatomite vs Chert information and Diatomite vs Chert characteristics in the upcoming sections.

Diatomite 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. Diatomite vs Chert characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diatomite and Properties of Chert. Learn more about Diatomite vs Chert in the next section.

More about Diatomite and Chert

Here you can know more about Diatomite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Chert consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, 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 Diatomite vs Chert, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Chert is available in black, brown, green, grey, red, white colors. Appearance of Diatomite is Soft and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Diatomite vs Chert. The hardness of Diatomite is 1 and that of Chert is 6.5-7. The types of Diatomite are Not Available 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 Diatomite and Chert is white. The specific heat capacity of Diatomite is 0.90 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.Diatomite is heat resistant whereas Chert is heat resistant, impact resistant, pressure resistant, wear resistant.
