Строение и основные этапы формирования погребенного (предпозднеплиоценового) рельефа Туркменистана

Аннотация

Detailed studies of drilling and geological and geophysical data revealed buried deeply dissected (to 800 meters) topography at Southern Turkmenistan, dated from Pre-Late Pliocene. The buried valley net of ancient Amu-Darya and its tributaries has been reconstructed and drawn in countourlines («paleo-isohypses») as well as river system southward from Kara-Bogaz-Gol, which was formed under conditions of low Caspian level during the end of Middle-beginning of Late Pliocene. A certain connection has been traced between the paleo-landforms on one side and tectonics and lithological and facial features of the Meso-Cenozoic series on the other side. The authors concluded that such great erosional features could substantially influence the hydrogeology, baric conditions etc., which in turn could influence the process of hydrocarbons migration, accumulation and conservation in the upper part of sedimentary mantle.
