The tectonic evolution of the western Tien Shan
… Cenozoic tectonic evolution of the western Tien Shan in Central Asia, which is one of the most active intracontinental ranges in the world. The work presented here combines a broad array of datasets, including thermo- and geochronology, paleoenvironmental interpretations, sediment provenance …

The orogenic evolution of the Central Kyrgyz Tien Shan
… orogenic evolution of the Central Kyrgyz Tien Shan in Central Asia, which is presently one of the most active intra-continental mountain belts in the world. This work involved combining a broad array of datasets, including thermochronologic, magnetostratigraphic, sediment provenance and …

SAR interferometry analysis of surface processes in the Pamir – Tien Shan active orogens - emphasis on coseismic deformation and landslides
… Alai valley. Located between the southern Tien Shan and the northern Pamir the coseismic surface displacements are analysed using SAR (Synthetic Aperture RADAR) data. The results show clear gradients in the vertical and horizontal directions along a complex pattern of surface ruptures and …

Source parameters of the major historical earthquakes in the Tien-Shan region from the late 19th to the early 20th century
The Tien-Shan and the neighboring Pamir region are two of the largest mountain belts in the world. Their deformation is dominated by intermontane basins bounded by active thrust and reverse faulting. The Tien-Shan mountain belt is characterized by a very high rate of seismicity along its margins as …

Tomographic inversion of Pn travel times in western China
… basins bordering the Tibetan Plateau (TP) and/or Tien Shan (Tarim, Junggar, Qaidam, and Sichuan basin) display prominent high Pn velocities. These basins are tectonically stable with little deformation and lacking in seismic, thermal, and volcanic activity. (2) Several portions including western …

The Proterozoic ancestry of the Colorado Mineral Belt : ca. 1.4 Ga shear zone system in central Colorado
… intracontinental zones of weakness like the Tien Shan, which record both original assembly of tectonic blocks and reactivation of intracontinental weaknesses during later plate convergence at a distant margin.

Glacier Monitoring in Ladakh and Zanskar, northwestern India
… used to map glaciers in the Khumbu Himal and the Tien Shan. This project aims first to test the ability of the morphometric procedure to map small glaciers; second, to use the morphometric approach to map glaciers in Ladakh; and third, to use Landsat and ASTER data and GPS and field measurements …

The Aral Sea : a palaeoclimate archive
… controlled by temperature variations in the Tien Shan and Pamir Mountains during the melting season, salinity and lake-level changes of the Aral Sea reflect temperature fluctuations in the high catchment area during the past 2000 years. Dinoflagellate cyst assemblages document lake lowstands …

Seismic hazard assessment in Central Asia
… reaches an intensity of around 8 in southern Tien Shan for a mean return period of 475 years. The maximum hazard estimated for some of the cities in the region, namely Bishkek, Dushanbe, Tashkent and Almaty, is between 7 and 8 (7-8), 8.0, 7.0 and 8.0 macroseismic intensity, respectively, for …

Modelling surface evolution coupled with tectonics
This study presents the development of 1D and 2D Surface Evolution Codes (SECs) and their coupling to any lithospheric-scale (thermo-)mechanical code with a quadrilateral structured surface mesh. Both SECs involve diffusion as approach for hillslope processes and the stream power law to reflect …
