... characteristics are considered. The results of the MT sounding inversion indicate the existence of a zone of lateral plastic flow in the Earth’s crust beneath the Alai depression, which manifested itself as a conductive lower-crust structure traced for at least 200 km in the E–W direction along the strike...

.... The Alai Valley between Trans Alai and Tien Shan is the vestige of a formerly contiguous Cenozoic sedimentary basin, which once linked the Tadjik Depression and parts of the Tarim Basin in the west and east ( Figs. 1 and 2 ), respectively ( Davidzon et al., 1982 ; Burtman, 2000 ). The thrust front...

...K.T. Pickering; T.N. Koren; V.N. Lytochkin; D.J. Siveter Abstract Analysis of Mid-Palaeozoic successions in the northern part of the Alai Range (Kyrgyzstan and bordering Uzbekistan), Southern Tien Shan, Central Asia, has identified a Silurian–Devonian deep-marine depositional system of basin-slope...

... these, especially the Devonian and Carboniferous seas of the Russian Platform, are particularly favorable areas, not only for paleontological but also for paleoecological and lithological studies. Somewhat later similar work was done for the seas of the foredeeps and the intermontane depressions, which...

The scheme of active faults of the Earth’s crust...

... there: the Chatkal-Kurama zone in the north ( q up to 108 mW/m 2 ) and the Fergana-Alai zone in the south ( q up to 75 mW/m 2 ). They are separated by the Fergana zone of abnormally low heat flow ( q up to 32 mW/m 2 ), which is related to the screening effect of the sediments of the Fergana depression...

DR3A–DR3F) and have 1–3 mm upward-coarsening laminations (Fig. DR2). These strata are interpreted as eolian dune deposits based on the following rationale...

He bases this conclusion on the close relationship observed between the bituminous lignite and the oil horizons...

... homogeneous earthquake distribution were identified as characteristic of distinct seismic regimes: (1) a segment of the range-bounding Gissar-Kokshal fault zone, (2) the interior of the crystalline massif of the Tien Shan mountain range, and (3) the Tadjik Depression fold-thrust belt. The pair analysis...

The thickness of Upper Triassic and Jurassic successions reached some 1600–2000 m in the Fergana depression, along the margins of the Fergana Range and Tien Shan (in areas of the recent Ili, Bagrash Kul, Kucha, and South Tajik basins, as well as the Alay valley of the Transalay Range...

An elongated low-velocity anomaly (L2; Figs. 4 and 5 ) that coincides with the Alai Valley located north of the Pamir orogen and becomes stronger at a 20 km depth is parallel to the Main Pamir Thrust. This anomaly...
