Marl vs Limestone

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.

Marl vs Limestone 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. Marl vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Marl and Properties of Limestone. Learn more about Marl vs Limestone in the next section.

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 0.80 kJ/Kg K 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.
