Formation
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Trachyte and Charnockite
Here you can know more about Trachyte and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyte and Charnockite consists of mineral content and compound content. The mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz and mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Trachyte vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Trachyte is Banded and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Trachyte vs Charnockite. The hardness of Trachyte is 6 and that of Charnockite is 6-7. The types of Trachyte are Not Available whereas types of Charnockite are Enderbite.
