Definition
Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

More about Charnockite and Marble
Here you can know more about Charnockite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Marble 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 Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Charnockite is Veined or Pebbled and that of Marble is Veined and Shiny. Properties of rock is another aspect for Charnockite vs Marble. The hardness of Charnockite is 6-7 and that of Marble is 3-4. The types of Charnockite are Enderbite whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Marble is white. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Marble 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.Charnockite is heat resistant, wear resistant whereas Marble is heat resistant.
