Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

More about Charnockite and Sandstone
Here you can know more about Charnockite and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Sandstone 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 Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Sandstone, 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, Sandstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Charnockite is Veined or Pebbled and that of Sandstone is Rough. Properties of rock is another aspect for Charnockite vs Sandstone. Hardness of Charnockite and Sandstone is 6-7. The types of Charnockite are Enderbite whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Sandstone is white. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Sandstone is 0.92 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 Sandstone is heat resistant, impact resistant, pressure resistant.
