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.

Granulite vs Marl 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. Granulite vs Marl characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Marl. Learn more about Granulite vs Marl in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Marl include Decorative aggregates and Floor tiles. Due to some exceptional properties of Granulite and Marl, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Marl include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
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 Not Available 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 Not Available. 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.
