Definition
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Diabase vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Serpentinite. Learn more about Diabase vs Serpentinite in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diabase and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Diabase and Serpentinite
Here you can know more about Diabase and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Serpentinite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Serpentinite, 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, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Diabase is Vesicular and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Diabase vs Serpentinite. The hardness of Diabase is 7 and that of Serpentinite is 3-5. The types of Diabase are Not Available whereas types of Serpentinite are Jadeitite. 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 Serpentinite is white, greenish white or grey. The specific heat capacity of Diabase is Not Available and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
