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'.
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism

Features
Host Rock for Lead

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.
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.

Serpentinite vs Slate 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 Slate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Slate. Learn more about Serpentinite vs Slate in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Slate include Bathrooms, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Serpentinite and Slate, 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 Slate include As dimension stone.
More about Serpentinite and Slate
Here you can know more about Serpentinite and Slate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Slate consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Slate includes Apatite, Biotite, Chlorite, Feldspar, Graphite, Hematite, Kaolinite, Magnetite, Pyrite, Tourmaline, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Slate, 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, Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors. Appearance of Serpentinite is Rough and Dull and that of Slate is Dull. Properties of rock is another aspect for Serpentinite vs Slate. The hardness of Serpentinite is 3-5 and that of Slate is 3-4. The types of Serpentinite are Jadeitite whereas types of Slate are Phyllite, Schist, and Slate. 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 Slate is light to dark brown. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Slate is 0.76 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 Slate is heat resistant, impact resistant, pressure resistant, wear resistant.
