Formation

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.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

Marl vs Carbonatite 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 Carbonatite Reserves. Marl is an unconsolidated sedimentary rock consisting of clay and lime. Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals. 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 Carbonatite information and Marl vs Carbonatite characteristics in the upcoming sections.

Marl vs Carbonatite 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 Carbonatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Marl and Properties of Carbonatite. Learn more about Marl vs Carbonatite in the next section. The interior uses of Marl include Decorative aggregates and Floor tiles whereas the interior uses of Carbonatite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Marl and Carbonatite, they have various applications in construction industry. The uses of Marl in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Carbonatite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Marl and Carbonatite

Here you can know more about Marl and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marl and Carbonatite consists of mineral content and compound content. The mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz and mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Marl vs Carbonatite, 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, Carbonatite is available in black, brown, green, grey, pink, white colors. Appearance of Marl is Rough and Dull and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Marl vs Carbonatite. The hardness of Marl is 2-3 and that of Carbonatite is 3. 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 Carbonatite are Carbonatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marl and Carbonatite is white. The specific heat capacity of Marl is 0.80 kJ/Kg K and that of Carbonatite is 0.51 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 Carbonatite is heat resistant, pressure resistant, water resistant.
