5 Formation

5.1 Formation

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.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Marl vs Limestone Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Marl and Limestone Reserves. Marl is an unconsolidated sedimentary rock consisting of clay and lime. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Marl vs Limestone information and Marl vs Limestone characteristics in the upcoming sections.

More about Marl and Limestone

Here you can know more about Marl and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marl and Limestone consists of mineral content and compound content. The mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Marl vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Marl is available in beige, brown, green, grey, white colors whereas, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Marl is Rough and Dull and that of Limestone is Rough and Banded. Properties of rock is another aspect for Marl vs Limestone. The hardness of Marl is 2-3 and that of Limestone is 3-4. The 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 whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marl and Limestone is white. The specific heat capacity of Marl is Not Available and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Marl is heat resistant, impact resistant whereas Limestone is pressure resistant.
