Definition
Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Charnockite vs Suevite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Charnockite vs Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Suevite. Learn more about Charnockite vs Suevite in the next section. The interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Charnockite and Suevite, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Charnockite and Suevite
Here you can know more about Charnockite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Suevite 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 Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Suevite, 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, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Charnockite is Veined or Pebbled and that of Suevite is Banded. Properties of rock is another aspect for Charnockite vs Suevite. The hardness of Charnockite is 6-7 and that of Suevite is 5.5. The types of Charnockite are Enderbite whereas types of Suevite are Phyllosilicates, Calcite. 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 Suevite is light to dark brown. The specific heat capacity of Charnockite is Not Available and that of Suevite 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 Suevite is heat resistant.
