Extracting Induced and Remanent Magnetizations
The computational processes involved in estimating the direction and intensity of magnetic remanence and the susceptibility are not entirely stable Generally, the best results are obtained with large Koenigsberger ratios (Q ≥ 1) When Q ≤ 1, the computed errors may be amplified, leading to unstable remanence direction and intensity 202 HD WASMUTHhighintensitymagneticseparators for thebeneficiation offeebly magnetic ores and for the removal of paramagnetic contaminants from industrial minerals The lowintensity magnetic separators used in commercial operation are mainly drumtype opengradient separators (OGMS) in which systems of permanent magnets made of barium ferrites generate magnetic field AG, (Received Hindawi Magnetic intensity is more than 1000nt lower than background 10km t Total magnetic intensity 002 magnetisation isosurface from the magnetic vector inversion Chile Santuario case the magnetic topography is thought to be a magnetic ignimbrite layer) • Modelling of deeper magnetic sources at low magnetic latitudes using Magnetics From the Arctic to the Andes identified a number of targets along the interpreted BIF trend where partial de‐magnetisation has occurred These areas are adjacent to major NE E trending shear zones, and possibly indicate the conversion of magnetite to non‐magnetic hematite or goethite, a hydrated form of iron oreENTERPRISE METALS LIMITEDMapping the patterns of magnetic anomalies attributable to rock magnetism has proved to be a very effective way of surveying large areas at low cost per unit area Permanent magnetism of rocks is an important attribute because it alone provides a memory of the intensity, direction, and polarity of the Earth's magnetic field as it existed at the Rock Magnetism geol
