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.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Diabase vs Whiteschist 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 Whiteschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Whiteschist. Learn more about Diabase vs Whiteschist in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Whiteschist include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diabase and Whiteschist, 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 Whiteschist include For road aggregate.
More about Diabase and Whiteschist
Here you can know more about Diabase and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Whiteschist consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Whiteschist, 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, Whiteschist is available in green, grey, white colors. Appearance of Diabase is Vesicular and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Diabase vs Whiteschist. The hardness of Diabase is 7 and that of Whiteschist is 1.5. The types of Diabase are Dolerite whereas types of Whiteschist are -. 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 Whiteschist is white. The specific heat capacity of Diabase is 0.84 kJ/Kg K and that of Whiteschist 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.Diabase is heat resistant, impact resistant, pressure resistant, wear resistant whereas Whiteschist is heat resistant.
