| Abstract: | This paper describes the basic principles and characteristics of the wider field electromagnetic method and the definition of apparent resistivity of the wider field.Exploration work was carried out in a silver,lead and zinc ore deposit of Inner Mongolia,including the deduction and interpretation of the anomaly.The result compared with CSAMT shows that the wider field electromagnetic method can achieve a larger exploration depth as well as higher exploration efficiency and precision with a smaller distance ... |
