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.

Mangerite 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 Mangerite 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 Mangerite Reserves. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture. Mangerite is a plutonic intrusive igneous rock, which is essentially a hypersthene-bearing monzonite. 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 Mangerite information and Chert vs Mangerite characteristics in the upcoming sections.
