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.

Geological and structural field works in Talas - Fergana fault zone.

Geological and structural field works in Talas - Fergana fault zone were performed by the joint scientific team of Research Station of RAS and the University Rennes, France.

In July of this year the next geological and structural field works in a zone of Talas-Fergana fault has been successfully completed. Marc Jolivet - the vice-director of the University Rennes (France), staff members Julien Morin and Gwladys Jolivet, employees of Research Station RAS Aleksandr Dzalba and driver Evgeny Ispolinov participated in this field works.

These works were performed under the Agreement on scientific and technical collaboration, which was signed in September 2015 between the Research Station RAS, IRC-GPG and the University Rennes, France, (Geosciences Rennes, Rennes France).

Within above-mentioned Agreement the following activities are expected:

• performance of joint research projects of geodynamic processes;
• organization and implementation of field works;
• more precise and efficient processing and interpretation of geological data on problems of modern geodynamic activity of orogenic areas lithosphere;
• preparation of joint publications in the international academic journals.

This Agreement promotes scientific cooperation between its participants in the course of solving fundamental problems of modern geodynamics of Central Asian continental lithosphere different segments, and topical applied problems of assessment the degree of orogenic territories and adjacent areas tectonic activity.

Within the works in Yarkand-Fergana basin the following scientific objectives have been appointed to 2018:

• To complement the logging of the late Triassic – Jurassic sections in the Sary Bulak Valley that was initiated in 2017.
• To sample those sections for biostratigraphic investigation (dating of the series) and       С-isotope analysis.
• To further explore the northern edge of the basin in order to describe the relation between the Jurassic sedimentary environment and tectonics.
• To describe the Jurassic sediments along the Talas Fergana fault to understand the role of this fault in the evaluation of the Yarkand Fergana basin.

Similar works are planned also to the summer of 2019.

Field works of MTS group

In June 2018 MTS group completed the works on search and selection of samples for determination of isotopic composition of helium in free and water-dissolved gases. Samples were obtained from mineral springs on the territory of Naryn oblast: Dostuk spring (area of Kulanak village), Karabuk spring (area of Orto-Syrt village), 2 Arashan springs (area of Besh-Bel-Chyr village) and Narzan springs (area of Kul-Suu Lake).

In July 2018, MTS group carried out MT soundings on three profiles in the Kochkor Valley of Kyrgyzstan. The observations were fulfilled by the magnetotelluric soundings method on 11 sites of "Ukok-2" profile, on 7 sites of "Chon-Tuz East» profile and on 7 sites of "Chon-Tuz in the West". The electric components of the MT-field were estimated using measuring complexes Phoenix MTU-5 and MTU-5A with electric dipoles 50m long. Measurement of the magnetic field components was performed with the help of MTS-50 induction sensors. At all sounding points dipoles were grounded by nonpolarizing electrodes. The duration of MT-field registration at each observation point was 15-16 hours.
