Formation
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.
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 Wackestone and Tephrite
Here you can know more about Wackestone and Tephrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wackestone and Tephrite consists of mineral content and compound content. The mineral content of Wackestone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz 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 Wackestone vs Tephrite, the texture, color and appearance plays an important role in determining the type of rock. Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Tephrite is available in black, brown, colourless, green, grey, white colors. Appearance of Wackestone is Rough and Dull and that of Tephrite is Vesicular. Properties of rock is another aspect for Wackestone vs Tephrite. The hardness of Wackestone is 2-3 and that of Tephrite is 6.5. The types of Wackestone are Marl, Shale and Argillite whereas types of Tephrite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wackestone is white while that of Tephrite is bluish black. The specific heat capacity of Wackestone is 0.39 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.Wackestone is heat resistant, impact resistant whereas Tephrite is heat resistant, impact resistant.
