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
Generally rough to touch, Is one of the oldest rock, Splintery, Very fine grained rock
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.

Clasts are smooth to touch, Easily splits into thin plates
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
