Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
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.

Laterite 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. Laterite vs Marl characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Marl. Learn more about Laterite vs Marl in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Marl include Decorative aggregates and Floor tiles. Due to some exceptional properties of Laterite and Marl, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Marl include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Laterite and Marl
Here you can know more about Laterite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Marl consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene and mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Laterite is Rough and Banded and that of Marl is Rough and Dull. Properties of rock is another aspect for Laterite vs Marl. The hardness of Laterite is 2 and that of Marl is 2-3. The types of Laterite are Not Available 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 Laterite and Marl is white.
