Definition
Marl is an unconsolidated sedimentary rock consisting of clay and lime
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Marl vs Suevite 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 Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Marl and Properties of Suevite. Learn more about Marl vs Suevite in the next section. The interior uses of Marl include Decorative aggregates and Floor tiles whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Marl and Suevite, 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 Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Marl and Suevite
Here you can know more about Marl and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marl and Suevite consists of mineral content and compound content. The mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Sedimentary Rocks. When we have to compare Marl vs Suevite, 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, Suevite is available in black, brown, green, grey, pink colors. Appearance of Marl is Rough and Dull and that of Suevite is Banded. Properties of rock is another aspect for Marl vs Suevite. The hardness of Marl is 2-3 and that of Suevite is 5.5. 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 Suevite are Phyllosilicates, Calcite. 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 Suevite is light to dark brown. The specific heat capacity of Marl is 0.80 kJ/Kg K and that of Suevite is 0.92 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 Suevite is heat resistant.
