Archaeological Significance
Formation
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 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 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. Suevite vs Marl characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Suevite and Properties of Marl. Learn more about Suevite vs Marl in the next section. The interior uses of Suevite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Marl include Decorative aggregates and Floor tiles. Due to some exceptional properties of Suevite and Marl, they have various applications in construction industry. The uses of Suevite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Marl include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Suevite and Marl
Here you can know more about Suevite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Marl consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite 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 Suevite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Suevite is available in black, brown, green, grey, pink colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Suevite is Banded and that of Marl is Rough and Dull. Properties of rock is another aspect for Suevite vs Marl. The hardness of Suevite is 5.5 and that of Marl is 2-3. The types of Suevite are Phyllosilicates, Calcite 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 Suevite is light to dark brown while that of Marl is white. The specific heat capacity of Suevite is 0.92 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.Suevite is heat resistant whereas Marl is heat resistant, impact resistant.
