摘要

地壳和上地幔中存在的电性各向异性是地电模型、地下结构和构造模型间一个重要的联系因素. 近年来, 它引起了广泛的关注, 推动了对电性各向异性结构模型和反演理论新方法的研究. 本文在Marquardt反演理论的基础上, 引入权因子对其改进后用于大地电磁视电阻率和阻抗相位联合反演, 通过具体算例的分析, 验证了理论的正确性; 此外, 对西北某地大地电磁实测资料处理解释, 说明了程序的实用性并为今后研究深部电性构造提供了一种新的方法和途径.

Abstract

The electrical anisotropy in the crust and the upper mantle is the main link among geoelectrical model, underlying structure, and tectonic model. In recent years, great attention was paid to this phenomenon, which promotes the new research towards the structure model of electrical anisotropy and inversion theory. According to the Marquardt's inversion theory, in the paper we first improve the weighting factor and apply it to the apparent resistivity and impedance phase joint inversion. Then, the detailed example analysis of them proves the corrctness of the mentioned theory. Additionally, the processing and the interpretation of the measured magnetotelluric data in northwest of china not only indicate the practicability of the theory, but also provide a new method for the future research of deep electrical structures.
