The paper presents a geodynamic iutelpretatioo of tbedeep strucillreand active tectonicsof
the northernTien Shan, with particullll'emphasis 00 strike-slipm~tioos,whidt prndu-ced
a pull-apart in the centreof the L,>syk-Kull:min. The stud)'is based 00 a detailed interpretation
of satellite imagery, fault plane solutions of earthquakes, seismic. and geodetic data.
Seismicand magnetotelluric studies showtectonic layeringof the Tien Shan lithosphere, with
several nearly horizontal viscoelastic layers and the lower layer underthrust northward in the
northern Tien Shan.This active process may be responsible for the intricate present-day tectonic
framework of the northern Tien Shan.
The recent tectonics of the northern Tien Shan inherits the earlier structure: The lens-shaped
Issyk-Kul microcontinent comprising Precambrian-Palaeozoic metamorphic and magmaticrocks
is surrounded by thick shear zones which have been involved in the activity over most of the
Cenozoic. In the Quaternary the strain propagated as far as the central part of the Issyk-Kul basin.
