Abstract:
The structure of the Central Pamirs is defined by piled-up large tectonic nappes, characterized by a quite definite and rather sustained sequence of stratification for the whole zone. Autochthone is represented by Early Proterozoic metamorphic complexes. It is structurally overlain by parautochthone, represented by Paleozoic and Meso-Cenozoic metamorphosed series stratified into two packages of tectonic plates, which were torn away from the basement. The autochthone and parautochthone constitute a zonally- metamorphosed basement complex saturated in Early Alpine granitoids. Granitoid massifs are usually confined to the cores of thermal anticlines. The basement complex is overlain by nonmetamorphosed allochthone, including five packages of tectonic plates; three of them are composed of disharmonious dislocated deposits of a local type, and the other two are represented by rack assemblages of adjacent zones. The southern slope of the Muzkol Range was selected for investigation as an extremely complicated region of the Central Pamirs, containing the most representative exposures of all the packages of tectonic plates of parautochthone and allochthone. The characteristic features of autochthone are given in our earlier works and in works of other researchers.
