Корреляция геологических комплексов горного массива Хан-Тенгри в пограничных районах Кыргызского, Казахского и Китайского Тянь-Шаня

Abstract

Researchers of the border regions in Kyrgyzstan, Kazachstan, and China discuss two two alternative models for the relationships between the main structural units of the Tianshan mountains. Most researchers believe that the Kyrgyz Middle Tianshan wedges out to the east along the Atbashi-Inylchek-Nalati marginal fault. According to another hypothesis, the Middle Tianshan structures continue within the range Nalati where they are described as Chinese Central Tianshan. Comparing the characteristics of the Paleozoic and Proterozoic sedimentary, volcanogenic, intrusive, and metamorphic formations of these regions leads us to the conclusion that the structural units of the Kyrgyz Middle and most of the Northern Tianshan, including the superimposed Middle-Late Paleozoic troughs, are not continued into China, but are successively cut along the echelon system of conjugated strike-slip faults, united by us into the Frontal Tianshan Dextral Strike-slip (FTDS). And only the northern segment of the Issyk-Kul terrane can be considered as an analogue of the Chinese Central Tianshan, displaced along the FTDS to the northwest for a distance over 80 km. Therefore, adjacent geological complexes are eroded along the FTDS similar to the oblique boundaries of convergent lithospheric plates affected by tectonic erosion.
