The Tien Shan and its adjacent areas have been a prime place to understand the process of continental collision, mechanism mountain building interaction tectonic blocks. In this study, we collect seismic data recorded by 74 broad-band stations from China Provincial Digital Seismic Networks Regional Kyrgyzstan Kazakhstan between January, 2007 September, 2009. A joint inversion technique that com...
An updated glacier inventory is important for understanding the current dynamics in conditions of actual accelerating retreat observed around world. Here, we present a detailed analysis glaciation areas Zhetysu Alatau Range (Tien Shan) 1956–2016 using well-established semiautomatic methods based on band ratios. The total area decreased by 49 ± 2.8% or 399 11.2 km2 from 813.6 22.8 to 414.6 11.6 ...
High-resolution major and trace element (Al, As, Ca, Cd, Co, Cr, Cu, Fe, Li, Mn, Na, Pb, S, Ti, and V) ice core records from Inilchek glacier (5120 m above sea level) on the northwestern margin of the Tibetan Plateau provide the first multi-decadal ice core record spanning the period 1908e1995 AD in central Tien Shan. The trace element records reveal pronounced temporal baseline trends and conc...
Detrital-zircon U-Pb geochronology is extensively used to imply provenance histories as one of the most common methods constrain tectonic evolution ancient sedimentary systems. The rapid accumulation detrital-zircon thermochronology data in eastern Tien Shan region brought great convenience for understanding basin–mountain region. In this work, 41 samples zircon dating from Jurassic–Cretaceous ...
We have studied the orogenic fragile deformation of upper Earth's crust several areas Eurasian continent, where deformations occurred many times -- in Tian Shan and Altai-Sayan regions Central Asian Paleozoic Fold Belt Baltic region Fennoscandian Shield (East European Platform). Our processing data on trends more than 4000 faults allows us to identify fault systems relationships among these sys...
