Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

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.
