Thermo-tectonic history of the Issyk-Kul basement (Kyrgyz Northern Tien Shan, Central Asia)

Abstract This paper presents an integrated geophysical study of the Western Central Asia (WCA) in the Uzbekistan area. It presents new interpretations of deep seismic sounding (DSS) data and new analyses of potential fields data. An integrated model of the physical properties and lithosphere structures displays distinct features that are related to tectonic history of the study WCA-Darius area. Task-oriented complex geological and geophysical research revealed in the lithosphere of western Uzbekistan series of crust blocks with abnormal petrophysical characteristics and established some correlation dependences between the distribution and placement of these objects (in plan) with deposits of minerals.

Insight Into

Central Asia hosts the Tianshan, the largest intracontinental mountain belt in the world, which experienced major reactivation and uplift since the Oligocene in response to the collision of India with Asia. This reactivation was focused around pre-existing structures inherited from the Paleozoic tectonic history of the region. The significant Cenozoic tectonic reworking of Central Asia complicates efforts to understand earlier phases of intracontinental tectonics during the late Paleozoic and Mesozoic. The Tarbagatai Mountains of eastern Kazakhstan record a thermotectonic history that provides insight into the timing and distribution of intracontinental tectonic activity in Central Asia prior to the India-Eurasia collision. Apatite fission track and (U-Th-Sm)/He analysis of igneous samples from the Tarbagatai Mountains reveals two episodes of cooling as a result of exhumation following Paleozoic amalgamation. Initial intracontinental deformation during the Late Permian drove exhumation synchronous with activity along newly formed strike-slip faults spanning the Central Asian Orogenic Belt. The major Chingiz-Tarbagatai Fault was reactivated during the Early Cretaceous, driving localised exhumation along the fault. The relative lack of Cenozoic tectonic activity in the Tarbagatai Mountains means they provide unique insight into the broader thermotectonic evolution of Central Asia during the late Paleozoic and Mesozoic.Supplementary material: Detailed thermochronological data, including plots and tables can be found in the supplementary data https://doi.org/10.6084/m9.figshare.c.5414555.

Nomadic Life

The people living in the Turkestan steppe region and usually known as “Kirghiz” call themselves “Kazakh”, and they are by customs and dialect different from their Turco-Tatar relatives who lead a half-nomadic life in the Tien Shan and in the Pamir Alay Mountains of Central Asia and who, though recorded in Western literature as “Buruts” or “Karakirghiz“, are the real Kirghiz. As they are one of the earliest known Turco-Tatar tribes, both the language and history of this little people merit some attention, all the more because since the foundationof the Kirghiz Socialist Soviet Republic (in 1924) the language has become aliterary one and, together with social and economic life, has developed a good deal.
