Definition
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'.
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt

Archaeological Significance
Formation
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.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

Serpentinite vs Gabbro 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. Serpentinite vs Gabbro characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Gabbro. Learn more about Serpentinite vs Gabbro in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Gabbro include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Serpentinite and Gabbro, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Gabbro include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Serpentinite and Gabbro
Here you can know more about Serpentinite and Gabbro. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Gabbro consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Gabbro includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Gabbro, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Gabbro is available in dark grey to black colors. Appearance of Serpentinite is Rough and Dull and that of Gabbro is Veined and Shiny. Properties of rock is another aspect for Serpentinite vs Gabbro. The hardness of Serpentinite is 3-5 and that of Gabbro is 7. The types of Serpentinite are Jadeitite whereas types of Gabbro are Anorthosite Gabbro and Norite Gabbro. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite is white, greenish white or grey while that of Gabbro is black. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Gabbro is 0.71 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Gabbro is impact resistant, pressure resistant, wear resistant.
