Nappe dislocations of collisional orogen (by the example of geological complexes on the southern slope of the Muzkol Range, central Pamirs)

The Central Pamirs are constructed of large tectonic nappes, whose stratification is quite clear and persistent throughout the zone. The autochthone is represented by Early Proterozoic metamorphic complexes. It is structurally overlain by the 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 disharmonically dislocated deposits of local type, and the other two are represented by rock associations 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.
