Abstract

The earth’s magnetic field is used to find the depth of anomalous sources as shallow as few metres to tens of kilometres. The deepest depths found from the magnetic field sometimes correspond to Curie depth, a depth in the crust where magnetic minerals lose their magnetic field due to increase in temperature. Estimation of depth from magnetic/aeromagnetic data generally assumes random and uncorrelated distribution of magnetic sources equivalent to white noise distribution. The white noise distribution is assumed because of mathematical simplicity and non-availability of information about source distribution, whereas from many borehole studies it is found that magnetic sources follow random and fractal distribution. The fractal distribution of sources found many applications in depth estimation from magnetic/aeromagnetic data. In this chapter Curie depth estimation from aeromagnetic data for fractal distribution of sources will be presented.
