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'.
Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers

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.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Serpentinite vs Chalk 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 Chalk characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Chalk. Learn more about Serpentinite vs Chalk in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Chalk include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Serpentinite and Chalk, 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 Chalk include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for manufacture of quicklime and slaked lime, Source of calcium.
More about Serpentinite and Chalk
Here you can know more about Serpentinite and Chalk. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Chalk consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Chalk, 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, Chalk is available in grey, white, yellow colors. Appearance of Serpentinite is Rough and Dull and that of Chalk is Soft. Properties of rock is another aspect for Serpentinite vs Chalk. The hardness of Serpentinite is 3-5 and that of Chalk is 1. The types of Serpentinite are Jadeitite whereas types of Chalk are Chalk Marl and Marl. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Chalk is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Chalk is 0.90 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 Chalk is heat resistant.
