5.1 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.

Tephrite vs Shoshonite 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 Shoshonite Reserves. Tephrite is an aphanitic to porphyritic textured, volcanic igneous rock. Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass. 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 Shoshonite information and Tephrite vs Shoshonite characteristics in the upcoming sections.

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