Mesozoic-Cenozoic Intramountain Basins of the Tien Shan and Western Transbaikalia: Comparative Characteristics and Correlation of Events Article 1. Question Formulation. Intramountain Basins of the Gissar-Alai and Central Tien Shan

A comparative analysis of Mesozoic-Cenozoic intramountain basins in the Eurasian intracontinental orogen reveals that these regions, including the Western and Central Tien Shan, were zones of dispersed shear flow. This dynamic process led to the formation and evolution of a system of depressions and uplifts, driven by the redistribution of rock masses during rheid deformation under conditions of vertical and lateral rheological heterogeneity in the crust. The study employs a multidisciplinary approach, including geological analysis, structural and tectonic research, geomapping, lithological section descriptions, experimental tectonophysics, and magnetotelluric sounding, to elucidate regional geodynamic development features. This first article in a series sets the foundation for further exploration of depressions in Western Transbaikalia and broader correlations of events.
