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.
  
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

Marl vs Phyllite 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 Phyllite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Marl and Properties of Phyllite. Learn more about Marl vs Phyllite in the next section. The interior uses of Marl include Decorative aggregates and Floor tiles whereas the interior uses of Phyllite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Marl and Phyllite, 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 Phyllite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar, Roadstone.
More about Marl and Phyllite
Here you can know more about Marl and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock.
