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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

Tephrite vs Diorite 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 Diorite Reserves. Tephrite is an aphanitic to porphyritic textured, volcanic igneous rock. Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene. 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 Diorite information and Tephrite vs Diorite characteristics in the upcoming sections.

Tephrite vs Diorite 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 Diorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tephrite and Properties of Diorite. Learn more about Tephrite vs Diorite in the next section. The interior uses of Tephrite include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Diorite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Tephrite and Diorite, they have various applications in construction industry. The uses of Tephrite in construction industry include Landscaping and that of Diorite include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate.

More about Tephrite and Diorite
