The Mikhnevo Seismic Group of the Institute of Geosphere Dynamics, Russian Academy of Sciences (IGD RAS), and the Malin mini-group in the region of the Dnieper–Donets aulacogen, within which prospecting and mountain-explosion works were carried out from 2007 to 2015 on industrial scales, recorded a series of seismic events. Special attention has been focused on analysis of the nature of three earthquakes in 2015. Application of the spectral discrimination method log(Pg/Lg) and cross-correlation tools allowed us to identify the seismic events in 2015 as a special technogenic-tectonic type. 相似文献

The combined approach is used for studying recent tectonic activity in the central part of the East European Craton (EEC).This approach incorporates the methods of automated lineament analysis and satellite geodesy with the conventional geological mapping analysis. The space tectonic map (space image based) is reconstructed, and morphostructures that are active at the recent and present tectonic stage are delineated by processing the Landsat image mosaic. The direction and rate of horizontal displacement of crustal blocks, which is caused by deep geodynamical processes, are determined using the GPS data. The study is preliminary since only few GPS stations within the EEC have sufficiently long time series of observations. 相似文献

The structure of magnetite lodes is determined by iron and sulfur distribution, as well as texture and structure of ore. These features have been revealed by documentation of cores from ore intervals in exploration boreholes penetrating two main lodes 21 and 22 of the Estyunino iron deposit. The documentation of cores was accompanied by sampling for microscopic examination of texture and structure of ore and selection of Fe and S contents in ore. Then these data were summarized as sections of the lodes. It was established that the structure of magnetite lodes is characterized by conformable ore layers distinguished by texture, structure, and Fe and S contents. Banded and spotty ores containing less than 50% magnetite are predominant. Layers of homogeneous massive ore are infrequent. The textural pattern indicates a volcaniclastic nature of host rocks. The spotty texture is characteristic of hyaloclastites with vitreous shards. The banded texture with oriented distribution of fiamme is inherent to volcaniclastic rocks. In both cases, magnetite selectively replaces dark-colored vitreous fragments and is also dispersed in the salic matrix and lava fragments. No indications of crosscutting superposed relationships are observed. The available data can be satisfactorily explained by an impregnation-metasomatic mode of ore deposition. 相似文献

Presented are the results of working out an extensive hydromonitoring system for water bodies based on the use of the optoelectronic phase level gage (as a water level meter) and cellular network (to transmit the digital data signal to the data acquisition and processing center). The “Riven’” telecommunication device converting information using the SMS-protocol is worked out for the connection of the phase level gage with the acquisition and processing center using the GSM system. Developed are the structure and algorithm of the hydromonitoring system. Produced is the level gage prototype for the hydrometric station. The hydromonitoring system is intended for the advanced flood warning of population and for providing environmental safety. 相似文献
