Abstract
During the late Palaeozoic, the area of the Kopet-Dagh had been accreted to the Turan plate and partly metamorphosed in greenschist facies, as were the Band-i-Turkestan, the North Hindu-Kush and the North Pamir. During Permian time, parts of these accreted terranes were uplifted, eroded and mainly the southern areas covered by red continental deposits. The Paleeotethys active margin migrated to the South and a new volcano-plutonic arc was emplaced South of the Hercynian collage, just to the North of the new Paleotethys subduction zone. During Triassic time, North of the plutonic arc and in a back arc setting, an arcuate deep subsiding volcano-sedimentary marine belt is recognised from the South Caucasus through the Kopet-Dagh to the North Pamir. A Cimmerian deformed segment of this back arc basin appears now in the erosional window of Aghdarband. From the study of the marine volcaniclastic facies and the Triassic events, a tentative model of the regional geodynamical evolution is presented.
