“…For the Kyzylkum segment of the STS, Seltmann et al 2011 give an overview of Early Permian post-collisional magmatism with emplacement ages of 293-276 Ma. In the Middle Tien Shan ages for the Permian post-collisional magmatism range from about 294 to 279 Ma (Alekseev et al, 2009;Konopelko et al, 2009;Seltmann et al, 2011). In the Kyrgyz Northern Tien Shan ages of 292 Ma are found (Glorie et al, 2010a;Seltmann et al, 2011).…”

“…During the Permian, this area was characterized by a dominant strike-slip deformation regime associated with ~E-W strike-slip faults and by the intrusion of granitic plutons (Alekseev et al, 2009;Biske et al, 2013;Chen et al, 2009;Choulet et al, 2012Choulet et al, , 2011Mikolaichuk et al, 1997;Seltmann et al, 2011;Wang et al, 2009). Whether Permian wrench tectonics took place in the continuity of Carboniferous deformations, or in a completely different setting is difficult to assess.…”

A pervasive magmatic event occurred in all the TS and was characterized by granitic intrusions cross-cutting the Paleozoic structures and following the trace of the strike-slip faults (Alekseev et al, 2009;Biske et al, 2013;Chen et al, 2009;Seltmann et al, 2011;. Mesozoic times are characterized by a long-lived erosion phase marked by a peneplain surface on which the Cenozoic formations were deposited Jolivet et al, 2010;Macaulay et al, 2014).…”

New structural data on Late Paleozoic tectonics in the Kyrgyz Tien Shan (Central Asian Orogenic Belt)

et al. 2017

The tectonic evolution of the Central Asian Orogenic Belt (CAOB) is characterized by the successive accretion of lithospheric blocks, leading to different interpretations about the polarity of subductions during the Paleozoic, the number of microplates and oceanic basins and the timing of tectonic events. This is especially the case in the Tien Shan area.In this paper, we propose new structural maps and cross-sections of Middle and South Kyrgyz Tien Shan (MTS and STS respectively). These cross-sections highlight an overall dextral strike-slip shear zone in the MTS at the crustal scale and a North verging structure in the STS. These structures are Carboniferous in age and sealed by a late Carboniferous conglomerate, later overlain by Mesozoic and Cenozoic deposits. The STS exhibits two deformation phases: (1) a top-to-the-South normal shearing that can be related to subduction or exhumation dynamics and (2) a top to the North nappe stacking that we link to the late Paleozoic collisional events between the MTS and the Tarim block.We propose a new interpretation of the tectonic evolution of the Kyrgyz Tien Shan during the Late Paleozoic collision. This model involves a partitioned collisional deformation in Late Carboniferous times, with an orthogonal collision to the south, between the Tarim and MTS, and a strike-slip regime to the north along a dextral E-W zone located between the MTS and the North Tien-Shan/ Kazakh platform, the so-called Nikolaev Line. The docking of the large Tarim Craton against the CAOB corresponds to a collision phase, which ended the longlived Paleozoic subduction history in the CAOB and was followed in the TS region by intense strike-slip deformation during the Permian.

“…From Middle Devonian to Late Carboniferous times, the Middle Tien Shan probably formed part of the passive margin of the Kazakh -Kyrgyz continent and was characterized by shallow-marine carbonate and siliciclastic sediments (e.g. Alekseev et al 2009;Biske & Seltmann 2010).…”

Geological evolution of Central Asian Basins and the western Tien Shan Range

The geological evolution of Central Asia commenced with the evolution of a complex Precambrian–Palaeozoic orogen. Cimmerian blocks were then accreted to the southern margin during the Mesozoic, leading to tectonic reactivation of older structures and discrete episodes of basin formation. The Indian and Arabian blocks collided with Asia during the Cenozoic, leading to renewed structural reactivation, intracontinental deformation and basin development. This complex evolution resulted in the present-day setting of an elongated Tien Shan range flanked by large Mesozoic–Cenozoic sedimentary basins with smaller intramontane basins distributed within the range. The aim of this volume is to present multidisciplinary results and reviews from research groups in Europe and Central Asia that focus on the western part of the Tien Shan and some of the large sedimentary basins in that area. These works elucidate the Late Palaeozoic–Cenozoic tectono-sedimentary evolution of the area. Emphasis is placed on the collision of terranes and/or continents and the ensuing fault reactivation; the impact of changes in climate on the sedimentation is also examined.
