Formation

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

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.

More about Turbidite and Tephrite

Here you can know more about Turbidite and Tephrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Tephrite consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Tephrite includes Alkali feldspar, Nepheline, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Tephrite, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, green, grey, pink colors whereas, Tephrite is available in black, brown, green, grey, white colors. Appearance of Turbidite is Dull and Banded and that of Tephrite is Vesicular. Properties of rock is another aspect for Turbidite vs Tephrite. The hardness of Turbidite is 3 and that of Tephrite is 6.5. The types of Turbidite are Sedimentary rock whereas types of Tephrite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Turbidite is white, greenish white or grey while that of Tephrite is bluish black. The specific heat capacity of Turbidite is 0.92 kJ/Kg K and that of Tephrite 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.Turbidite is heat resistant whereas Tephrite is heat resistant, impact resistant.
