Archaeological Significance
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
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.

Evaporite 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. Evaporite vs Marl characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Marl. Learn more about Evaporite vs Marl in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Marl include Decorative aggregates and Floor tiles. Due to some exceptional properties of Evaporite and Marl, they have various applications in construction industry. The uses of Evaporite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, 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 Evaporite and Marl
Here you can know more about Evaporite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Marl consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in green, grey, silver, white colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Marl is Rough and Dull. Properties of rock is another aspect for Evaporite vs Marl. Hardness of Evaporite and Marl is 2-3. The types of Evaporite are Sedimentary 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 Evaporite and Marl is white. The specific heat capacity of Evaporite 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.Evaporite is heat resistant, pressure resistant whereas Marl is heat resistant, impact resistant.
