Formation

Formation
Tephrite 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.   
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Tephrite vs Enderbite 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 Tephrite and Enderbite Reserves. Tephrite is an aphanitic to porphyritic textured, volcanic igneous rock. Enderbite rock is an igneous rock which belongs to the Charnockite rock series. 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 Tephrite vs Enderbite information and Tephrite vs Enderbite characteristics in the upcoming sections.
