| Abstract: | This paper describes new methods suitable for aeromagnetic interpretationof special magnetic fields, which include intensification of weak signal, self-adjusting filter and analytic signal. The purpose for adopting these methodsis to obtain information related to ore-prospecting indicators and geologicalstructures which is not shown distinctly in the initial data.The application ofthese methods to the analysis of aeromagnetic data from the weak magneticarea of southern Hunan and the volcanics area of Inner Mingolia has provedthat these methods are effective in improving geological mapping. |
