Field works of Magnetotelluric Studies Group (GMTS). “Kentor” profiles.

In the course of magnetotelluric observations conducted at “Kentor” profiles since 2012, the MTS Group conducted MT soundings (MTS) at 34 sites of “Centralnyi” (С1 - С11) and “Vostochnyi” (Е1 – Е11, Е13 - Е22, Е24, Е26) profiles in the period from October 1 to October 14, 2018.

The MTS test record to monitor the noise level was conducted at C8 site.

Works were preceded by calibration of recorders and sensors. For estimation of noise level and parameter settings, test recording was conducted at all observation sites. Magnetic field components were measured using МТС-50 induction sensors. Electric components of MT-field were measured by measuring equipment with 50-meter electric dipoles. The dipoles were earthed using nonpolarizable electrodes by the “electrode to electrode” principle with previous observations at all sounding sites.

Orientations of measuring equipment completely reproduced the previous deployments. Duration of MT-field registration at each observation site was 15-16 hours.

Works were complicated by adverse weather conditions.

Day of the Bishkek Proving Ground.

Traditionally, we celebrate the Day of the Bishkek Proving Ground on October 18, the birthday of Yuri Trapeznikov, founder and first Director of the Research Station of RAS.

This year, due to weather conditions, the meeting in honor of this event was held on October 22. Anatoly Rybin, the Director of RS RAS, had a short speech, when he addressed the RS RAS and that despite unfavorable exterior, we all need to maintain a high level of research and scientific activities set by the founders and employees of RS RAS. Director emphasized the importance of the continuity of generations of scientists, engineering researchers and the entire staff for the well-being and successful development of Research Station.

Joint field study

In August and September of 2018, the joint field study on the basis of Research Station RAS in Bishkek city with participation of staff members of GIN RAS, Moscow (Alekseev D.V.), St. Petersburg State University (Hudolya A.K., Moskalenko A.N., Kushnareva A.V.) and A.P. Karpinsky Russian Geological Research Institute (VSEGEI) (Tolmacheva T.Yu.) was conducted. This works were aimed to study stratigraphy, geochronology and structural evolution of Precambrian and early Paleozoic complexes of the Northern Tien Shan. As a result, the detailed structural characteristic of a mesoproterozoic Kochkor complex and its analogs in Talas district, early Paleozoic ensembles of Aktyuz, Makbalsk and Talas complexes were obtained and conodont fauna age of siliceous and volcanic series of an early Paleozoic Kyrgyz Terskeysky sutura zone were specified. In order to conduct geochronological, paleontologic, geochemical and structural, geological studies the set of samples was collected and passed to GIN RAS laboratories, VSEGEI and St.Petersburg State University for processing.

Introductory tour for the students and lecturers of the Kyrgyz National University

On September 21, 2018, twenty 1 – 3 year students and their lecturers of Physics and Electronics Departments of the Kyrgyz National University had an introductory tour around the territory of the Research Station. This excursion was organized under the Agreement on scientific and technical cooperation between the Research Station of Russian Academy of Sciences and Kyrgyz National University named after Jusup Balasagyn.

The excursion started with RS RAS Director Dr. Anatoly Rybin’s presentation, in which he highlighted the main milestones of establishment and activity of Research Station. Then the guests got the opportunity to know more about five RS RAS laboratories activities (Laboratory of Integrated Studies of Dynamic Processes in Geophysical Fields (LIS), Laboratory of Studying Modern Movements of the Earth’s Crust by Space Geodesy (LGPS), The Laboratory of Deep Magnetotelluric Studies (LDMS), Laboratory of Advanced Hardware Development (LAHD), Laboratory of Energy-Saturated Media Simulation (LESMS). Heads and staff members of laboratories told guests about the tasks and important results of the laboratories activity in popular manner. KNU students showed keen interest and desire to participate in scientific events organized by Research Station in future.

The 24th EM Induction Workshop, Helsingør, Denmark, 13–20 Aug 2018

Dr. Anatoly Rybin, Director of Research Station, took part in 24^th EM Induction Workshop (EMIW2018), which took place in Helsinger, Denmark, 13-20 August 2018.

Dr. Anatoly Rybin presented poster report:

A. Rybin, E. Bataleva, Yu. Morozov, M. Leonov, E. Przhiyalgovski³, V. Matukov and O. Zabinyakova Zones of concentrated deformation in the Central Tien Shan: geoelectric images and tectonic interpretation.

The results obtained within RSF project №16-17-10059 implementation were observed in above mentioned paper.

Abstract:

In the paper results of the detailed magnetotelluric soundings executed for the last years in the territory of the Central Tien Shan and focused on the study of the concentrated deformation zones are presented. Parameters of detailed geoelectric sections of Kochkor, Naryn and Atbashi intermountain basins are discussed in the sense of their tectonic interpretation. New tectonic constrains, based on a complex interpretation of the upper crust structure of the investigated areas, including structural geology study of the Cenozoic sedimentary cover, the crustal geoelectric sections, the structural unconformities and occurrences of recent deformations in the basement rocks, are revealed.

The geoelectric model of the southern margin of the Kochkor basin reflects the complex system of folded and fault structures of this tectonic zone. The geometry and allocation of conducting zones in the geoelectric structure may indicate that, deformation of basement surface was mostly ductile and now is manifested in the tectonic structure by folds with oversteep basement/sediment stratigraphic and complex structure of basement block surfaces within the basin.
