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.

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

More about Marl and Turbidite

Here you can know more about Marl and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marl and Turbidite consists of mineral content and compound content. The mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Marl vs Turbidite, 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, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Marl is Rough and Dull and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Marl vs Turbidite. The hardness of Marl is 2-3 and that of Turbidite is 3. 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 Turbidite are Sedimentary rock. 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 Turbidite is white, greenish white or grey. The specific heat capacity of Marl is 0.80 kJ/Kg K and that of Turbidite 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 Turbidite is heat resistant.
