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.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

More about Marl and Jaspillite
Here you can know more about Marl and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marl and Jaspillite consists of mineral content and compound content. The mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz and mineral content of Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Marl vs Jaspillite, 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, Jaspillite is available in red, reddish brown colors. Appearance of Marl is Rough and Dull and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Marl vs Jaspillite. The hardness of Marl is 2-3 and that of Jaspillite 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 Jaspillite are Algoma-type , Lake Superior-type and Superior-type.
