Definition
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
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.

More about Diamictite and Marl
Here you can know more about Diamictite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Marl consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz 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 Diamictite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Diamictite is Banded and that of Marl is Rough and Dull. Properties of rock is another aspect for Diamictite vs Marl. Hardness of Diamictite and Marl is 2-3. The types of Diamictite are Bedded Diamictite and Laminated Diamictite 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 Diamictite is light to dark brown while that of Marl is white. The specific heat capacity of Diamictite is 0.75 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.Diamictite is heat resistant, impact resistant whereas Marl is heat resistant, impact resistant.
