Textural and Compositional Study of Sefidrud near shore Sediments

In this study efforted Using field Sampling and Sedimentary Analysis to display Textural andCompositional of Sefidrud Near shore Sediments. And with the Sedimentological parameters such as Mean, Skewness and Sorting, sedimentary process and sediment resource distinguished. Sampling and statistical analyses of the grain size distributions of coast (Back shore, Dunes, Beach Ridge, Lagoon, Sand plain) and Sefid Rud river mouth sediments at various locations along the coastline show that they varied in their mean grain size and values of sorting and skewness. The statistical parameters of grain size distributions thus allowed recognition of distinct sub environments. The size distribution of such sediments suggests that the various processes that are responsible for their transportation and deposition are wave, current and wind action and scatter plot of standard deviation versus skewness distinguished coast samples are bimodal and river samples are polymodal. Also with detection of heavy mineral and X-Ray and sediment cross section, show that magnetite and Illmenite and quartz, feldspar and plagioclase are the most important heavy minerals and rock fragments as respectively.
