Аннотация

There are results of the electrical resistivity tomography of the Syuldyukarskaya kimberlite pipe in Yakutia. The main goal of this work is to assess the capabilities of the method when working in permafrost conditions and overlying low-resistivity polarizing rocks. The pipe has the form of a steeply dipping stratum limited along the strike. Fieldworks were carried out a parallel profiles network, two-dimensional arrays were combined into a three-dimensional dataset, the automatic 3-D inversion was performed. The resistivity sections and in the 3-D model seen that the pipe distinguishes by a steeply dipping low resistivity anomaly and an anomaly of increased polarizability from the lying side of the stratum. The induced polarization (IP) anomaly is more intense in the upper part than on the pipe deeper that is associated with abundant pyritization. The local IP anomalies in the overlying sediments are even more intense and have a stratum form. The IP anomaly has a steeply dipping stratum form in the contours of the pipe. The electrotomography has shown high efficiency and is recommended for use in studying geological sections within magnetic anomalies.
