The database contains a digital version of the physical properties data for South African rocks. Physical properties include density (kg/m3); Magnetic properties include magnetic susceptibility (X10-5), intensity of natural remanent magnetization (A/m) with direction of magnetization (if available), Königberger ratio (Q) and Paleomagnetic data; Electrical properties include time-domain resistivity (Ohm-m) and Induced polarization (% or mV/V), frequency-domain resistivity (Ohm-m) and spectral induced polarization (mS/m); Dielectric parameters include permittivity (e'), noise attenuation (dB/m) and wave propagation (m/ns); Seismic properties include P-wave and S-wave acoustic velocities (m/s).
