Geophysical Survey of a Mud Volcano Chongeleksky

Summary Changelessly mud volcano refers to bulganakskoie type with the constant mode of eruption and irregular placement of griffins and Salz. The volcano is located in the core of the Tobechik anticline, the axis of which, presumably, sinks under the bottom of the Tobechik lake and extends to the NORTH. In order to assess the possibility of using non-seismic geophysical methods in the study of such geological formations, a set of ground-based geophysical studies was performed on the South shore of lake Tobechik, including electrotomography (ERT), the natural electric field (SP) method, surface water resistivity, area survey of the magnetic field, kappametry, profile observations of gravity field anomalies, radiometry, registration of emanations, thermometry and petrophysical modeling of resistivity. Based on the results of ground-based geophysical studies, the studied profiles make it possible to understand the structure of the Chongelek mud volcano, which is consistent with the geological concepts of the structure of such objects. Given a more dense network of observations, involving research in the lake area and aerial photography of the area using UAVs, we can talk about the possibility of studying the structure of such phenomena using non-seismic methods.
