5 Formation
5.1 Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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.
