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

Present

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.
