Archaeological Significance
Formation
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.
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 Jaspillite and Marl
Here you can know more about Jaspillite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jaspillite and Marl consists of mineral content and compound content. The mineral content of Jaspillite includes Coesite, Quartz, Sand 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 Jaspillite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Jaspillite is available in red, reddish brown colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Jaspillite is Banded and Glassy and that of Marl is Rough and Dull. Properties of rock is another aspect for Jaspillite vs Marl. The hardness of Jaspillite is 3 and that of Marl is 2-3. The types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type 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 Jaspillite and Marl is white. The specific heat capacity of Jaspillite is 3.20 kJ/Kg K and that of Marl is 0.80 kJ/Kg K.
