Abstract

Base on appearing numerous problems in spreading flood stations, caused by fine grains sediments after flood sedimentary, like decreasing the permeability and hardening of the soil and also, producing 15000 ton sedimentary clay and silt during two floods in spreading flood station of Kabudar Ahang and decreasing the permeability rate about 0.35 cm/h this survey aims to determine the provenance of these sediments, in order to control them. For this reason, after producing the map of drainage net and watershed, there obtained about 60 samples from fine sediments main drainage, spreading flood area, sedimentation basin and soils. Also, 18 lithic samples were obtained from different lithologies, of which 8 samples analyzed by the method of x-ray differactometery (X.R.D). Another 18 samples analyzed by the method of neutron activation analysis to calculate R.E.E. rate, "Th" and "Sc" elements. There is also 9 samples analyzed by the method of producing thin section. At first, geological map was drawn, by the help of results, second RE.E. rates were normalized based on cl-chondrites and Post Archaen Australian Average shale (P.A.A.S), as the base values. Then scatter and pattern diagrams and their abundance were drawn after calculating different factors like La/Sm,… , Eu/Eu* in addition abundance diagrams of "Th", "Se" and "La/Th", "Th/Sc" rates were also drawn and studied. results were: Pattern diagram of Naser Abad drainage and samples of PS formation, were simillar and parallel with samples of sedimentation basin. Also, they show good genetic relationship in scatter diagrams. This shows that sources of fine grain sediments of spreading flood station are from soils of PS formation at the end of Naser Abad drainage, Gand tapeh and Gavzian villages. Base on the result of this study and other surveys, first, studing R.E.E will be useful for PROVENANCE OF SEDIMENTS, and second, different subwatersheds which are producing similar minerals, studying their by X.R.D. is not helpful and no produce reliable results.
