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'.
Marl is an unconsolidated sedimentary rock consisting of clay and lime

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.
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.

Serpentinite vs Marl 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 Marl characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Marl. Learn more about Serpentinite vs Marl in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Marl include Decorative aggregates and Floor tiles. Due to some exceptional properties of Serpentinite and Marl, 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 Marl include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Serpentinite and Marl
Here you can know more about Serpentinite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Marl consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Serpentinite is Rough and Dull and that of Marl is Rough and Dull. Properties of rock is another aspect for Serpentinite vs Marl. The hardness of Serpentinite is 3-5 and that of Marl is 2-3. The types of Serpentinite are Jadeitite whereas types of Marl are Clay Marl ,Blue Marl, Red Marl, High Bank Marl, Shell Layer Marl, Under Shell Layer Marl, Sand Marl, Green Marl, Grey Marl and Clayey Marl. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Marl is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Marl is Not Available. 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 Marl is heat resistant, impact resistant.
