CHEMICAL AND MINERALOGICAL ANALYSIS FOR PROVENANING OF THE BRONZE AGE POTTERY FROM SHAHR-I-SOKHTA, SOUTH EASTERN IRANWritten by Zeinab Javanshah
The present study has typologically selected fifteen potsherds from Bronze age site of Shahr-i-Sokhta (Iran) analysed by X-Ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM) with Energy Dispersive XRay Spectroscopy (EDS) to determine the mineralogical, chemical, and morphological characteristics of the pottery samples. Thin-Section Petrography is also utilized to evaluate the XRD and XRF results and to identify the texture and the geographical status of the samples and X-Ray Diffraction (XRD) is used to determine their mineralogy. The clay fabric was fine and common texture is of high siliceous matter and include calcareous and non-calcareous clay types with high refractory. The presence of diopside, albite and analcime minerals in the shards points to a firing temperature that lies in the 900°C in an oxidizing atmosphere. It is concluded that all Shahr-i-Sokhta pottery shard samples could be described as local pottery with sandy clay from the same source.
