Abstract

We consider a method for interpretation of magnetotelluric sounding (MTS) for the area of the Ketkino field of thermal water (KFTW) acquired using a precision station. We describe the relevant methodology and the theoretical part in the analysis of raw materials. We have performed a qualitative estimate of the geoelectric medium based on MT data. Given the results of this estimation and the number of sounding points, we have carried out 1D inversion based on selected curves. Comparison is made between the results of 1D inversion and the geological section on the one hand and the distribution of thermal water temperatures in near-surface medium based on drilling data as described in archival reports on the other.

大地电磁测深技术在堪察加Ketkino温泉田地电特征研究中的应用体会
本文研究了一种利用精密测量站采集的Ketkino热水田(KFTW)地区大地电磁测深(MTS)的解释方法。介绍了原材料分析的相关方法和理论部分。我们根据大地电磁资料对地电介质进行了定性估计。考虑到估算结果和测点数量,我们选择曲线进行了一维反演。将一维反演结果与地质剖面进行对比,将档案报告中基于钻井资料的近地表介质热水温度分布进行对比。

期刊介绍: Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
