( NIGTC FEB RAS) // vitstepanov@yandex.ru BEREZITOVOYE GOLD ORE DEPOSIT: HISTORY OF DISCOVERY, OPERATION AND STUDY The history of discovery, exploitation and exploration of the average reserves of the Berezitovoye gold-polymetallic deposit in the Amur region is considered. It was discovered in 1932 and has been exploited in a quarry since 2007. A review is given of numerous publications in scientific journals, as well as dissertation and monographs on the geological structure, ore composition and genesis of the deposit. The significant contribution of the employees of the Institute of the Far East Geological Institute of the Far East Branch of the Russian Academy of Sciences in the study of the Berezitovoye deposit is noted. Recommendations for further prospecting for deposits of this type are given in publications devoted to the Berezitovoye ore cluster and gold-silver-polymetallic deposits of the Amur region.

Results of exploration electrical resistivity and carbonatization in the Jurassic layers of 200 wells and also spontaneous potential variation, electrical resistivity and natural radioactivity in Bazhenov suite establish anomalousness of geophysical and petrophysical parameters of Jurassic rocks in case of pre-Jurassic deposits. This paper determines 6 geophysical and petrophysical characteristics of the Jurassic layers as predictive indicators for oil and gas potential estimation in pre-Jurassic section. Keywords: pre-Jurassic oil and gas complex, anomalousness of geophysical and petrophysical characteristics of the Jurassic layers, assessment of Paleozoic oil and gas potential, Tomsk region.

(Hydrospetsgeology) // dm_russia@mail.ru METHODS OF PROCESSING AND INTERPRETATION OF MONITORING DATA WHEN ASSESSING GROUNDWATER CONTAMINATION CONSIDERING THEIR AGE The hydrogeological monitoring data processing and interpretation approach for retrospective estimation of the impact assessment of industrial storage basin on groundwater was developed. As is shown the consideration of the groundwater age at the model calibration allows getting the refined information on the intensity of source of groundwater contamination and improves the reliability of model forecast calculation. Keywords: hydrogeological simulation, groundwater age, estimation of industrial source of groundwater contamination. Р. 29-38 |

The dependences of the magnetic treatment of drilling mud on the time of exposure to tension and temperature are shown. It is proved that the rate of sludge deposition of nanostructured, highly inhibited drilling mud increases twice when magnetized in a constant magnetic field with a strength of 320 kA/m. Keywords: sedimentation, sludge coagulation, device for magnetization, drilling mud. Р. 45-50 |
