Formation

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

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.
