Peat is a highly organic soil, consisting almost entirely of vegetable matter in varying stages of decomposition. It is brown to black in colour and possess a strong organic odour. Peat in general is highly compressible and hence one should be cautions while using if for supporting foundations of structures.
Muck is a mixture of fine particles, inorganic solid and black decomposed organic matter. It is usually found accumulated under conditions of imperfect drainage e.g. in swamps or is deposited by overflowing rivers. Indurated clay is a soil that had been hardened by extremes of climate.
