Formation
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Diabase vs Charnockite 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. Diabase vs Charnockite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Charnockite. Learn more about Diabase vs Charnockite in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Diabase and Charnockite, they have various applications in construction industry. The uses of Diabase in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Charnockite include As dimension stone.
More about Diabase and Charnockite
Here you can know more about Diabase and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Charnockite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine 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 Diabase vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Diabase is Vesicular and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Diabase vs Charnockite. The hardness of Diabase is 7 and that of Charnockite is 6-7. The types of Diabase are Dolerite whereas types of Charnockite are Enderbite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diabase is black while that of Charnockite is white. The specific heat capacity of Diabase is 0.84 kJ/Kg K and that of Charnockite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diabase is heat resistant, impact resistant, pressure resistant, wear resistant whereas Charnockite is heat resistant, wear resistant.
