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.   
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Tephrite vs Laterite 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 Laterite Reserves. Tephrite is an aphanitic to porphyritic textured, volcanic igneous rock. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. 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 Laterite information and Tephrite vs Laterite characteristics in the upcoming sections.

More about Tephrite and Laterite

Here you can know more about Tephrite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tephrite and Laterite consists of mineral content and compound content. The mineral content of Tephrite includes Alkali feldspar, Nepheline, Plagioclase, Pyroxene and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Tephrite vs Laterite, 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, Laterite is available in brown, buff, red colors. Appearance of Tephrite is Vesicular and that of Laterite is Rough and Banded. Properties of rock is another aspect for Tephrite vs Laterite. The hardness of Tephrite is 6.5 and that of Laterite is 2. The types of Tephrite are Not Available whereas types of Laterite are Not Available. 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 Laterite is white. The specific heat capacity of Tephrite is 0.92 kJ/Kg K and that of Laterite is Not Available. 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 Laterite is heat resistant, pressure resistant.
