Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

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.

More about Granulite and Marl

Here you can know more about Granulite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Marl consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Granulite is Veined or Pebbled and that of Marl is Rough and Dull. Properties of rock is another aspect for Granulite vs Marl. The hardness of Granulite is 6-7 and that of Marl is 2-3. The types of Granulite are Metamorphic rock 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 Granulite and Marl is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Marl is 0.80 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Marl is heat resistant, impact resistant.
