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 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 Tephrite and Latite Reserves. Tephrite is an aphanitic to porphyritic textured, volcanic igneous rock. 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 Tephrite vs Latite information and Tephrite vs Latite characteristics in the upcoming sections.

More about Tephrite and Latite

Here you can know more about Tephrite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tephrite and Latite consists of mineral content and compound content. The mineral content of Tephrite includes Alkali feldspar, Nepheline, Plagioclase, Pyroxene and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Tephrite vs Latite, the texture, color and appearance plays an important role in determining the type of rock. Tephrite is available in black, brown, colourless, green, grey, white colors whereas, Latite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Tephrite is Vesicular and that of Latite is Rough. Properties of rock is another aspect for Tephrite vs Latite. The hardness of Tephrite is 6.5 and that of Latite is 5-5.5. The types of Tephrite are Not Available 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 Tephrite is bluish black while that of Latite is white. The specific heat capacity of Tephrite is 0.92 kJ/Kg K and that of Latite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tephrite is heat resistant, impact resistant whereas Latite is heat resistant, pressure resistant.
