Monitoring of geofields in the Kola Superdeep geolaboratory: History, experience, basic challenges and results

The results for investigation of geoacoustic noises distribution in a range of 100-5000 Hz along the Kola Superdeep Borehole (SG-3) have been discussed. A geological section cut by the borehole in the interval of 300-6840 m is shown to be dynamically active by parameters of three-component measurements of geoacoustic noises (GAN). When comparing the data obtained at a year intervals, we found a vertical migration of zones of the stressed state of rocks that is fixed by appearance of new GAN local anomalies or disappearance of those found earlier. From the analysis of the GAN amplitude-frequency spectra, gas emission from the rock massif has been observed, in particular, at the zones of tectonic dislocation of the geological environment.

Signatures of fluid level variations in the Kola Superdeep and two surrounding boreholes

Modern concepts of the deep structure of the earth crust based on the analysis and generalization of seismic data collected in the past 40 years and the Kola Superdeep Borehole record have been presented. The tomographic model of the Pechenga district has been characterized. Our knowledge of the layered pattern of the earth crust stratification has been updated, the geometry of seismic boundaries has been described more accurately and the crust-mantle boundary under the Pechenga structure has been found to be uplifted.
