Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

Formation
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 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 vs Diabase 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. Whiteschist vs Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Whiteschist and Properties of Diabase. Learn more about Whiteschist vs Diabase in the next section. The interior uses of Whiteschist include Decorative aggregates and Interior decoration whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Whiteschist and Diabase, they have various applications in construction industry. The uses of Whiteschist in construction industry include For road aggregate and that of Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Whiteschist and Diabase
Here you can know more about Whiteschist and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Diabase consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Diabase is available in dark grey to black colors. Appearance of Whiteschist is Banded and Foilated and that of Diabase is Vesicular. Properties of rock is another aspect for Whiteschist vs Diabase. The hardness of Whiteschist is 1.5 and that of Diabase is 7. The types of Whiteschist are - whereas types of Diabase are Dolerite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Whiteschist is white while that of Diabase is black. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Diabase 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.Whiteschist is heat resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
