Abstract

Today, there is very little information about the presence of Parthian people on the shores of the Persian Gulf. Therefore, it is very difficult to identify the Parthian sites of southeast Iran. Due to the low awareness about the characteristics of the Parthian pottery of this region, this paper has focused on the analysis of the constituent elements of rough black pottery and to be its local or non-local origin. This research is a descriptive, analytical and adaptive study to answer the following questions: What are the characteristics of Qeshm potteries? What are the elements of coarse black pottery? What are the similarities between the coarse black pottery of Qeshm and those from neighboring areas? For the aims, 12 pottery samples from three sites of Dofari (QS 6), Gorbadan (QS 72) and LenjSazi 3 (QS 132) were selected to analyze by using polarized light microscopy (PLM). Results showed that 100% of the cases had a porphyry structure and the presence of void space was also observed in 100% of the cases. The presence of grog, calcite, sparite and micrite fragments were recorded in 75, 83.33 and 41.66% of the potteries, respectively. Quartz mineral, hematite, plagioclase and periclase were also presented in 91.66, 75, 50 and 75 percent, respectively. In terms of geological location, Qeshm Island is located in the fold zone of Zagros. Therefore, the presence of carbonate and sandstone sedimentary units in pottery is not far from expected. In addition, most of the filling elements of the pieces are of igneous and sedimentary origin. Our findings show that, the originated soils of the Qeshm potteries have the same context/elements. This analyzes also indicates that these potteries were made in the place and not imported. As the result, Qeshm Parthian potteries have a potentially structural similarity with those from the southern coasts of the Persian Gulf (e.g., UAE, Bahrain and Oman), especially Makran.
