Figure 17. The geological and geophysical profile reflecting the modern structure, crustal structure, and Alpine geodynamics of the South Tien Shan region. This model was derived using the data published in the literature (more than 40 references given in [Leonov, 1993]), and my own data. (1) Neogene-Quaternary molasse; (2) the Mesozoic-Paleogene deposits of the Fergana and Afgan-Tajik basins; (3) salt-bearing rocks; (4) subsalt rocks; (5) Mz-Kz deposits in the internal basins of the Gissar-Alai mountain system; (6) Paleozoic deposits of the sedimentary-metamorphic rock complex that had accumulated by the end of the Paleozoic; (7) "granite-metamorphic" (upper crust) layer; (8) potential regions of melt origin, inferred from geothermal and gravity data (with Paleozoic granites found at shallow depths); (9) lower-crust "basic" rock layer; (10) relatively cold upper mantle; (11) relatively hot low-density mantle (asthenospheric layer); (12) potential trace of the Paleozoic marginal subduction zone; (13) the surface of the pre-Mesozoic basement (pre-Mesozoic peneplane); (14) Conrad discontinuity; (15) Moho discontinuity; (16) overthrusts and faults in the top of the crustal layer; (17) the conventional boundary between the low-conductivity (cold) and high-conductivity (hot and low-density) mantle (the cross-hatched areas denote the boundary zones recorded by magnetotelluric sounding); (18) tectonic flow trends; (19) general subhorizontal compression stress; (20-22) the values of resistivity (20), seismic velocity (21), and density (22).
