Models of frequency-dependent susceptibility of rocks and soils revisited and broadened
Original language description
Mathematical models of the frequency-dependent susceptibility in rocks, soils and environmental materials have been adapted to measurements performed with multiple operating frequencies (465, 976, 3904, 4650, 15 616, 100 000 and 250 000 Hz) on the basisof log-normal volume distribution of magnetic particles. The X(FD) parameter depends, in addition to the amount of SP particles, also on the operating frequencies, whose values should be therefore also presented. The model curves of the X(FD) parameter versus arithmetical mean (mu) of the logarithms of grain volume are roughly bell-like shaped. The width and peak position of these curves is controlled by mean and standard deviation of the logarithmic volume distribution. Magnetic susceptibility contributions from paramagnetic minerals, and from ferrimagnetic particles not belonging to a unimodal SP/SD volume distribution, tend to decrease the X(FD) parameter. Therefore, low X(FD) values do not therefore necessarily indicate low amount o
