Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye.

More about Enderbite and Porphyry
Here you can know more about Enderbite and Porphyry. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Enderbite and Porphyry 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 Porphyry includes Biotite, Chert, Feldspar, Garnet, Graphite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Enderbite vs Porphyry, 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, Porphyry is available in black, brown, colourless, green, grey, red, rust, white colors. Appearance of Enderbite is Veined or Pebbled and that of Porphyry is Dull. Properties of rock is another aspect for Enderbite vs Porphyry. Hardness of Enderbite and Porphyry is 6-7. The types of Enderbite are Not Available whereas types of Porphyry are Rhomb Porphyry. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Enderbite and Porphyry is white. The specific heat capacity of Enderbite is Not Available and that of Porphyry is Not Available. 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 Porphyry is heat resistant, impact resistant.
