Definition
Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar
Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

More about Charnockite and Argillite
Here you can know more about Charnockite and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Argillite consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Charnockite is Veined or Pebbled and that of Argillite is Rough and Dull. Properties of rock is another aspect for Charnockite vs Argillite. The hardness of Charnockite is 6-7 and that of Argillite is 2-3. The types of Charnockite are Enderbite whereas types of Argillite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite is white while that of Argillite is white to grey.
