The article defines (through the viewpoint of nappe tectonics) structural features of Lower-Jurassic structural-substantial complex of the Azerbaijan part of Greater Caucasus. Conclusions and summarizations are based upon the current understanding of the tectonic stratification of alpine cover and pre-Jurassic basement of the mountain range. This understanding proceeds from the outcomes of latest geological research implemented in its Azerbaijan part. Defined are Shakhnabad-Jimi, Tufan, Saribash and Talachay-Duruja allochthon complexes subsequently thrusted upon each other in the North-South direction, and together – upon the northern side of the South Caucasus microplate. Allochthon complexes originate from sub-phases of Later-Cimmerian deformations of the tangential compression in the area of underthrust-overthrust interaction of Southern and Northern Caucasus continental microplates.
