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.
