Figure 3. The map of the structural and formation zones of the South Tien Shan: (1-8) Hercynian formations: (1) old basement rocks (Garm Massif of metamorphic rocks), (2) sedimentary rocks of the median and marginal massifs: (a) autochthonous, (b) allochthonous; (3) rocks from Early Hercynian central uplifts: (a) with the development of early metamorphism, (b) with the development of high-grade metamorphism (Turkestan Complex); (4) same with the wide development of batholith-type granitoids (South Gissar Zone); (5) rocks in Early Hercynian foredeeps; (6) rocks in volcanic "island-arc'' troughs; (7, 8) rocks that had accumulated during the epi-Hercynean evolution phase: (7) in marginal foredeeps, and (8) in internal fault-related basins; (9) anticlinoria; (10) synclinorium; (11) alpine formations.
The framed areas are the following study areas: the Alai Range (1), the Baubashata Mountain Assembly (2), the Turkestan Range (3), and the Zeravshan-Gissar Range (4). The largest fold structural features are the Kauzan (I), Kichikalai (II), Khodzhaachkan (III), and Kulgedzhili (IV) anticlinoria, and the Aravan (V), Okhna-Taldyk (VI), Surmetash (VII), and Daraut-Turkestan (Kurganak) (VIII) synclinoria.
The Baubashata area includes the Kainda (IX) and Seresui (X) anticlinoria (megaanticlines) and the Isfandzhailoo (XI), Kerei (XII), and Sarybel-Mailisu (XIII) megasynclines.
The Turkestan area includes the Malguzar (XIV) and Zeravshan-Turkestan anticlinoria, and the Fan-Margib (XX) and Zidda-Karakul (XXI) synclinoria.
