Abstract：Bagtiyarlyk block is located on the middle-south of the Chareju zone,a tectonic zone of Karakum Basin.There is a set of salt and gypsum with huge thickness in Kimmeridgian formation of upper Jurassic.The huge salt and gypsum could be deformed easily under high temperature and high pressure.Therefore it is very difficult to recover tectonic history on the plastic deformation area.So this study emphasize on verifying the tectonic characters in plastic deformed area by analyzing basin evolution,tectonic history of un-deformed area,deposition history of salt and gypsum,mechanism of plastic deformation.The final purpose is to eliminate the false response of ancient structure on under-layers caused by the plastic deformed layers.According to the above described,we conclude some methods which may clarify the real tectonic history on the plastic deformed area.
