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.

Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Chert vs Latite 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 Latite Reserves. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic 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 Chert vs Latite information and Chert vs Latite characteristics in the upcoming sections.

More about Chert and Latite

Here you can know more about Chert and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chert and Latite consists of mineral content and compound content. The mineral content of Chert includes Quartz, Silicon and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Chert vs Latite, 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, Latite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Chert is Glassy or Pearly and that of Latite is Rough. Properties of rock is another aspect for Chert vs Latite. The hardness of Chert is 6.5-7 and that of Latite is 5-5.5. The types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chert and Latite is white. The specific heat capacity of Chert is 0.74 kJ/Kg K and that of Latite is 0.92 kJ/Kg K.
