Тhe task of searching for kimberlite pipes in covered areas of the Yakutia kimberlite province is very difficult due to the significant heterogeneity of the rocks overlying kimberlite pipes. The overlying strata of terrigenous sediments contain rocks of the trap complex (dolerite sills, tuff bodies). We consider the results of the controlled source...

The paper considers different modes of producing a "rotating" field for the implementation of the tensor CSRMT method. We analyzed changes in the direction of polarization of a high-frequency electromagnetic field of a grounded wire used as a source in the CSRMT method, depending on the frequency and wire parameters. Modelling results and field exp...
Article
In this paper, we discuss several approaches for a joint inversion of controlled source radiomagnetotelluric (CSRMT) and electrical resistivity tomography (ERT) data observed over anisotropic media. We compare results of 2D isotropic joint inversion with results of a newly developed joint 1D anisotropic inversion algorithm. The developed algorithm...
Conference Paper
Audiomagnetotellurics (AMT) is a well-established geophysical method, which is widely used in mineral exploration. Still, three-dimensional numerical simulation of the electromagnetic field remains a very resource-intensive procedure. It is especially true for the high-frequency three-dimensional AMT surveys, where a high conductivity contrast and...

Controlled source radiomagnetotelluric (CSRMT) measurements with a horizontal electrical dipole were carried out for the planned construction of a railway bridge in the Northern part of Siberia (the Yamalo-Nenets region). The aim of this survey was the delineation of horizons of loams, which are mostly thixotropic, and the estimation of the depth o...

This paper presents a novel numerical method for simulation controlled-source audio-magnetotellurics (CSAMT) and radio-magnetotellurics (CSRMT) data. These methods are widely used in mineral exploration. Interpretation of the CSAMT and CSRMT data collected over an area with the complex geology requires application of effective methods of numerical...

Congress theme: Engineering geophysics The radiomagnetotelluric (RMT) method has been applied successfully to different environmental, engineering and geological targets in the last ten years. It uses military and civilian radio transmitters broadcasting in a frequency range between 10 kHz and 1 MHz as active source. A significant disadvantage of t...

Electrical resistivity anisotropy of rocks has significant influence on measurements and interpretation of electrical and electromagnetic data. Hence, the estimation of anisotropy can provide additional and accurate information about the subsurface. Its negligence during the inversion can lead to erroneous results. Capabilities of the near surface...

The present work focuses on the estimation of anisotropy and its influence on the interpretation. Anisotropy of the subsurface is estimated using the transition zone measurements of Controlled-Source Radiomagnetotellurics (CSRMT) field measurements. In addition, the electrical resistivity measurements were also conducted The CSRMT results are compa...

The resistivity anisotropy is an important parameter for interpretation of electromagnetic soundings data. The importance of anisotropy was demonstrated by the marine electromagnetic community. Significant anisotropy is also observed in near surface media. In this abstracts we are discussing the detectability of anisotropy using land-based controll...

Horizontal welling is a common method for the laying of the pipelines. This technology requires detailed exploration of first 20-30 m of subsurface for searching the optimal path for the welling tools and minimization of the damaging risks. Situations when the pipeline trace crosses the river are very common. In such a case, it becomes necessa...

In the course of near surface measurements, we investigated the application of the controlled source radiomagnetotelluric (CSRMT) sounding method. The used equipment RMT-C includes a five-channel recorder (frequency range 1–1000 kHz), two electric and three magnetic sensors, and a transmitter (1 kW) with a horizontal electric dipole as a source. Th...

The possibilities of estimating the macroanisotropic parameters of the earth by radiomagnetotelluric soundings with a controlled source in the form of a horizontal electric dipole (a cable with a finite length) are studied in the case of the measurements in the transition zone of the source, where the galvanic and induction modes of the excited ele...

A normal electromagnetic field of the high-frequency horizontal electric dipole is analyzed with allowance for the displacement currents in the earth and air. The components of the field are calculated by the method of partial integration for nonsmooth behavior of the integrand. The boundary between the quasistationary and wave zone of the source i...

The wave zone for a horizontal electric dipole (HED) as a source in the controlled source radiomagnetotelluric (CSRMT) method at the use of high frequencies (hundreds kilohertz) is allocated. The following features of the wave zone compare to the quasi-static one are noted: slower EM field attenuation with distance, changes of position of a favorab...

Mobile (car-borne) modification of the radiomagnetotelluric (RMT) method ensures measurements of the surface impedance in frequency band 10-1000 kHz and realization soundings in movement. Surveys are realized using ungrounded (capacitive) electric lines at different type of surface cover (soil, asphalt, snow etc.). 5-7 km/h speed of a car provides...
