Origination of Wind Deposits in the East of Zabol by Using Of Morphoscopy and Physical & Chemical Analysis of Sediments

The plain of Sistan has great erodibility because of the existence of alluvial and fine sand blast. Considering 120days winds and the drought of the region, this fine sand blasts were easily dislocated and form sand dune in different shapes. Field investigations interpret that the source of regional sediments is originated to the Pleistocene and new sediments that is the deposits of the lake of Hamoon,s bed has been recently dried, and covered with deltaic deposits of Sistan rivers such as Parnian, Niatak with tens of meters of thickness. Part of this Aeolian sediments is originated from the lake deposits, and the rest of the sand may be carried by winds especially 120 days winds from western and farther region which is not due to be studied here. Western plains of Hamoon River are of those areas which may be considered as a source of these sand places. In this paper, we are to determine the origin of sediments using the methods of physical and chemical analysis such as XRD, BET, TGA and DSC spectral interpretation of different phases of samples and sediments morphoscopy. If the experiments show the similar gender and morphoscopy of samples, it means that the source of all these sediments are the same, otherwise they can have different source and origin.
