Archaeologically, the Rudbar plain is one of the richest and most outstanding regions in the south east of Iran. The Tomb-e Kharg, is the largest site in this region. The site is a multi-period, but based on the surface material, the main settlement belongs to the historical period. What with these periods remaining unknown in the south-eastern Iran and lack of any reference to them in the authentic authorities, this region calls for a particularly urgent archeological research as an underlying and reliable reference. To do this, a topographic map of the hill, as well as the grid map, in which the region was divided into 10×10m2 were laid out. By means of simple random sampling method 10% of the squares were then sampled. In the light of the study on the collected cultural material, the main settlement dates back to a period ranging from the first millennium BC up to the 8th or 9th AD centuries. Moreover, there are some items of painted grey ware, suggesting that this hill leads back to 3th millennium BC.
