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.

Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Marl vs Basalt 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 Basalt Reserves. Marl is an unconsolidated sedimentary rock consisting of clay and lime. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth. 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 Basalt information and Marl vs Basalt characteristics in the upcoming sections.

More about Marl and Basalt

Here you can know more about Marl and Basalt. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marl and Basalt consists of mineral content and compound content. The mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz and mineral content of Basalt includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Marl vs Basalt, 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, Basalt is available in black, brown, light to dark grey colors. Appearance of Marl is Rough and Dull and that of Basalt is Dull and Soft. Properties of rock is another aspect for Marl vs Basalt. The hardness of Marl is 2-3 and that of Basalt is 6. 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 Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marl is white while that of Basalt is white to grey. The specific heat capacity of Marl is 0.80 kJ/Kg K and that of Basalt is 0.84 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 Basalt is heat resistant, pressure resistant, wear resistant.
