Characterization and peculiarities of a typical basalt residual soil profile
The properties of a soil are influenced by geological conditions, local climate and mineralogy. The analyzed soil profile, derived from basalt, is constituted by two sets: superior (evolved soil – Latosol) and inferior (saprolite). With increasing depth, NSPT and moisture values tended to increase a...

| Sumario: | The properties of a soil are influenced by geological conditions, local climate and mineralogy. The analyzed soil profile, derived from basalt, is constituted by two sets: superior (evolved soil – Latosol) and inferior (saprolite). With increasing depth, NSPT and moisture values tended to increase and clay fraction decreased, while plasticity index increased, assuming the existence of a clay blockage in the upper set. The evolved soil exhibited a bimodal pore distribution with a predominance of interaggregated pores (70%) and a reduction in size of the larger pores with increasing depth. These peculiarities are useful in defining geotechnical parameters and justify values, not always consistent with those expected, for fine soils. |
