Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Picrite 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 Enderbite and Picrite
Here you can know more about Enderbite and Picrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Enderbite and Picrite consists of mineral content and compound content. The mineral content of Enderbite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite. You can also check out the list of all Igneous Rocks. When we have to compare Enderbite vs Picrite, the texture, color and appearance plays an important role in determining the type of rock. Enderbite is available in black, grey, orange, pink, white colors whereas, Picrite is available in black, brown, green, grey, pink, white, yellow colors. Appearance of Enderbite is Veined or Pebbled and that of Picrite is Rough and Shiny. Properties of rock is another aspect for Enderbite vs Picrite. The hardness of Enderbite is 6-7 and that of Picrite is 6.8. The types of Enderbite are - whereas types of Picrite are Oceanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Enderbite is white while that of Picrite is white, greenish white or grey. The specific heat capacity of Enderbite is 0.79 kJ/Kg K and that of Picrite is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Enderbite is heat resistant, wear resistant whereas Picrite is heat resistant.
