Abstract:

This paper deals with the principles of computation method for joint interpretation of the apparent resistivities and impedance phases from magnetotelluric data. Analysis of concrete actual examples indicates that the method is correct and effective. This method is more predominant in respect of reducing solutions than is inversion method for pure apparent resistivity data or impedance phase data.

Key words: Magnetotelluric, Apparent resistivity and impedance phase, Joint inversion, Earth’s electrical model, Resolution

摘要：

本文叙述了大地电磁视电阻率和阻抗相位资料联合解释的原理与计算方法。通过具体算例的分析,表明该方法是正确有效的,而且在缩小多解性方面,要比单纯的视电阻率资料反演法或阻抗相位资料反演法优越。
