10Be exposure dating of river terraces at the southern mountain front of the Dzungarian Alatau (SE Kazakhstan) reveals rate of thrust faulting over the past ~ 400 ka

Abstract: The mountain belts of the Dzungarian Alatau (SE Kazakhstan) and the Tien Shan are part of the actively deforming India–Asia collision zone but how the strain is partitioned on individual faults remains poorly known. Here we use terrace mapping, topographic profiling, and 10Be exposure dating to constrain the slip rate of the 160-km-long Usek thrust fault, which defines the southern front of the Dzungarian Alatau. In the eastern part of the fault, where the Usek River has formed five terraces (T1–T5), the Usek … Show more

“…Red lines mark faults discussed here in detail: Al = Altyn Emel Fault, Ch = Chilik‐Chon‐Kemin Fault zone, Dz = Southern Dzhungarian Range Front Fault, Ka = Kalinino Fault, Kc = Fault near Kapchagay reservoir, Ko = Konyrolen Fault, Sh = Shonzhy Fault. Blue lines are active faults discussed in previous studies: Ar = Almaty Range Front Fault (Grützner, Walker, et al, ), Kk = Karkara Faults (Mackenzie et al, ), Se = Almaty Range Front Fault (Selander et al, ), To = Toraigyr Fault (Grützner, Carson, et al, ), Us = Usek Thrust (Cording et al, ). The surface ruptures of the 1889 Chilik earthquake are marked in green (Abdrakhmatov et al, ); brown lines are those of the 1911 Chon Kemin earthquake (Arrowsmith et al, ).…”

“…It is bounded by major E‐W thrust faults to the north and to the south, and by a NE‐SW left‐lateral strike‐slip zone in the west (Figure a). Close to the western basin margin, a number of smaller faults with a NW‐SE trend are also observed (Figure b; e.g., Cording et al, ; Kober et al, ). So far little is known about the active tectonics of the western Ili Basin and what role it plays in accommodating shortening and shear.…”

“…1). In its western part, close to the Junggar Alatau and the Sa-Iliskii Alatau mountains, persistent compression of Central Asian lithosphere led to folding and uplift of the basin margins (Kober et al, 2013;Cording et al, 2014). Over the past 50 years, different lithostratigraphic subdivisions have been proposed for the sedimentary succession of the basin, leading to overlapping unit names and incoherent boundaries (e.g.…”

“…Note that this dating approach is not peculiar to alluvial fans; it can be performed on other fault-displaced landforms too, such as fluvial terraces (e.g. Cording et al 2014), or outwash terraces and moraines (e.g. Rood et al 2011).…”
