摘要

摘要介绍了一个三维电阻率模型，该模型包含三个结构层次上形状复杂的电阻率异常：沉积覆盖层、固结地壳和上地幔。分析了通过解决直接问题而获得的合成（模型）磁电探测数据，以确定与不同深度非均质电阻率相关的异常。我们还给出了磁强计数据各组成部分对这些非均质性的敏感性的定量估计。此外，我们还计划利用所提供的数据来评估解决反问题的各种方法的效率。

Sensitivity of Magnetotelluric Soundings to Typical Electrical Conductivity Anomalies in the Tectonosphere

Abstract

A three-dimensional resistivity model is presented that contains electrical resistivity anomalies of a complex shape on three structural levels: in the sedimentary cover, in the consolidated crust, and in the upper mantle. The synthetic (model) magnetotelluric data obtained as a result of solving the direct problem are analyzed to identify anomalies associated with resistivity in inhomogeneities at different depths. Quantitative estimates of the sensitivity of various components of the magnetotelluric data to these inhomogeneities are given. Further, we plan to use the presented data to evaluate the efficiency of various methods for solving inverse problems.
