“…Improved detection in magnetic environments could be achieved by having control of the direction of the primary field. As mentioned earlier in this report, variations in transmitter fields were explored in detail by Pasion et al (2002b).…”

“…We use the same earth model as Pasion et al (2002b) which comprises a 1m thick magnetically viscous layer over a basement with no magnetic viscosity. The field from this layered earth, as illustrated in Figure 3.1, is considerably different than the r 3 falloff of the sphere.…”

“…The effects of superparamagnetic (SPM) material on transient EM data has been well documented and analysed for ground EM surveys in mineral exploration (Buselli, 1984;Lee, 1984;Barsukov and Fainberg, 2001), archaeological studies (Tabbagh and Dabas, 1996) and UXO detection (Billings et al, 2003;Pasion et al, 2002). SPM is mainly caused by the presence of very small particles of iron oxide, which generally occur at the surface but can also be found in palaeochannels at considerable depth.…”

“…Чаще всего проявления магнитной вязкости геологических сред связаны с установлением и релаксацией намагниченности однодоменных зерен ферримагнитных минералов -явлением суперпарамагнетизма [Большаков, 1996]. В большинстве случаев, например в палеомагнитных исследованиях [Encyclopedia…, 2007], а так-же при интерпретации данных импульсной индуктивной электроразведки [Buselli, 1982;Lee, 1984a,b;Захаркин и др., 1988;Dabas, Skinner, 1993;Pasion et al, 2002] проявления магнитной вязкости рассмат-ривают как геологическую помеху.…”

“…С другой стороны, эффекты магнитной вязкости отражают важные особенности генезиса и стро-ения природных и антропогенных геологических сред и объектов, а также происходящих в верхних горизонтах земной коры геологических процессов [Кожевников, Снопков, 1990Барсуков, Файн-берг, 1997, 2002Kozhevnikov et al, 2001Kozhevnikov et al, , 2003Кожевников, Антонов, 2008;Стогний и др., 2010;Казан-ский и др., 2012].…”
